Citation: Allen LN, Jun Fu, Pritchard JK, Wellendorf R, Allen RW. Cannabis produces THCA-Synthase (Not-Psychoactive). THCA-Synthase is produced by the RAW cannabis plant while it grows in the soil. Often thought to be the direct precursor to THC, recent studies have shown that THCa is actually the precursor to CBGa (cannabigerolic-acid), which then gets converted to THC through oxidocyclization, with the natural assistance of the enzyme THCa-synthase. scuba0504 , Jun 24, 2009 The enzymes that produce THC and CBD are encoded by synthase genes called THCA and CBDA. THCA and CBDA are both derived from cannabigerolic acid (CBGA). CBGA is also the parent compound to THCA, via the enzyme THCA synthase. The final products of THC and CBD are formed via decarboxylation of these acidic forms. thca synthase later showed that classification using just the CBD/THC values will mask the existence of chemotypes with relatively high amounts of other cannabinoids [10]. THCA synthase catalyzes a unique oxidative cyclization of the geranyl group of CBGA. The presence and relative quantities of the specific enzymes are what controls which cannabinoid is the major product from each particular strain. Why Cannabigerolic Acid (CBGa) is Kind of a Big Deal the THCA synthase (THCAS) converts CBGA to THCA, while CBDA synthase (CBDAS) forms CBDA and CBCA synthase A PCR marker Linked to a THCA synthase Polymorphism is a Reliable Tool to Discriminate Potentially THC‐Rich Plants of Cannabis sativa L. To transform THCA into THC (III), THCA needs only to heated. Post-translational N-linked glycosylation increases the total mass to approximately 74 kDa. By. Transgenic tobacco hairy roots expressing THCA synthase can produce THCA upon feeding of CBGA. And in doing so, Cooper explains, Ebbu is focusing on treating cannabinoids themselves as a commodity. These plants must humidity, light and temperature cured for THCA-Synthase & CBDA-Synthase to fold in CBGA and produce THCA-A, B, C (Still Non-Psychoactive) in Cannabis and CBDA in Hemp.

Cannabigerol (CBG) You Need To Know What This Is. The structural similarity between CBDA synthase and THCA synthase suggests that the CBDA synthase The THCA synthase enzyme is a member of the p-cresol methyl-hydroxylase superfamily, and the tertiary structure is divided into two domains (domains I and II), with a flavin adenine dinucleotide coenzyme positioned between each domain and covalently bound to His114 and Cys176 (located in domain I). Alternative Name(s) Delta(1)-tetrahydrocannabinolic acid synthase. 5 g CDW l-1 before enzyme activity was lost. THCA-S is the end of the bio-synthetic pathway for Cannabis. From that article “Examination of the THCA/CBDA ratio in plants of intermediate phenotype suggests that THCA synthase and CBDA synthase might not be equally competitive for CBGA, the precusor Tetrahydrocannabinolic acid (THCA) synthase is the enzyme responsible for the making of tetrahydrocannabinol (THC), the psychoactive constituent of marijuana (Cannabis sativa L. Finally, 1 mM (0. It bears structural similarity to the other natural cannabinoids, including tetrahydrocannabinol, tetrahydrocannabivarin, cannabidiol, and cannabinol, among others. Subsequent decarboxylation of THCA and CBDA via light exposure, heating, or aging, For example, Teewinot produces the Cannabis enzymes THCA synthase and CBDA synthase in a microorganism. Cannabigerolic (CBG) Is Vital To The Development Of Cannabis. Cannabis produces CBD-carboxylic acid through the same metabolic pathway as THC, until the last step, where CBDA synthase performs catalysis instead of THCA synthase. During biocatalysis, both reactions proceed in a pH-dependent manner in a bioreactor. The region coding for 545 residues was amplified using the primers 5′-CGGGATCCATGAATTGCTCAGCATTTT-3′ and 5′-CTAGCTGAGCTCTTAATGATGATGCGGTG-3′.

THCA and cannabigerolic acid (CBGA), its substrate, were shown to be apoptosis-inducing agents that might play a role in plant defense. Authors: Yoshinari Shoyama 1 Research Centre United States. The THCa decarboxylase and it lose that Carboxylic-acid and form THC. Epub 2013 Jun 20. Pastoris to transform molecule (I), a THC precursor, to THCA (II). A cutting-edge research company in Colorado is working on editing the cannabis genome, producing single-cannabinoid strains, massive fields of clones and plants that can produce trichomes on their fan leaves. It’s a precursor to tetrahydrocannabinolic acid (THCA) and cannabichromene acid (CBCA). One prevailing theory focuses on the genetic production of THC and CBD. Part of the cannabinoids biosynthetic pathway in the plant Cannabis sativa. General pathway for biosynthesis This enzyme converts CBG into THCA, which becomes THC when heated. The Δ9-tetrahydrocannabinolic acid synthase (THCAS) from Cannabis sativa was expressed intracellularly in different organisms to investigate the potential of a biotechnological production of Δ9-tetrahydrocannabinolic acid (THCA) using whole cells. X-ray crystal structure of THCA synthase was determined to 2. The ¢nal step, the decarboxylation of THCA to THC, might be a non-enzymatic reaction and can be caused by external factors such as temperature and light in the course of drying and storage [5]. thca synthaseTetrahydrocannabinolic acid (THCA) synthase is an enzyme responsible for catalyzing the formation of THCA from cannabigerolic acid (CBGA). In a preferred aspect of the invention, the C5-C10 cyclic It is the precursor to the three major branches of cannabinoids: tetrahydrocannabinolic acid (THCA), cannabidiolic acid (CBDA), and cannabichromenic acid (CBCA). First isolated in Israel by Dr. THCA synthase might contribute to the self-defense of Cannabis plants by producing both THCA and hydrogen peroxide, but since these reaction products are toxic to the plant itself, THCA synthase must be secreted from secretory cells into the storage cavity to avoid cellular damage. A comparative analysis of the sequences obtained with others available sequences of the THC synthase gene in GenBank revealed a major polymorphism of THCA synthase gene in The enzymes making THC and CBD are encoded by THCA and CBDA synthase genes, respectively. form of the THCA synthase gene and a thymine in the inactive form of the THCA synthase gene. , 2004), and an 8% THCA production in tobacco hairy roots (Nicotiana tabacum cv. Cannabigerolic acid (CBGA), the precursor to all natural cannabinoids, is cyclized into tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA) by THCA and CBDA synthase, respectively. Canna-bucha? (working on names, obviously) Five Guys Blocked Unblock Follow Following. The idea was to inhibit the THCA Synthase enzyme and create a plant that only produces the medicinal non-euphoric component CBD, a highless cannabis plant. I would wager using THC distilate will be unfruitful, THCA is crystalline, THC is not. CBD Synthesis CBGA is turned into CBD acid and THC acid by enzymes called CBDA synthase and THCA synthase. Conversely, Sativa strains code for greater amounts of CBDA synthase, which converts CBG into CBDA, a CBD precursor. Tetrahydrocannabinolic acid (THCA, 2-COOH-THC; conjugate base tetrahydrocannabinolate) is a precursor of tetrahydrocannabinol (THC), the active component of cannabis. codes for CBDA synthase where the other codes for THCA synthase. sativa THCA synthase would provide growers, providers, distributors, and users of medical marijuana with more pertinent information about the quality of C. Read "Analysis of THCA synthase gene expression in cannabis: A preliminary study by real-time quantitative PCR, Forensic Science International" on DeepDyve, the largest online rental service for scholarly research with thousands of academic publications available at your fingertips. Structure and function of 1-tetrahydrocannabinolic acid (THCA) synthase, the enzyme controlling the psychoactivity of Cannabis sativa. Cannabigerol is found in higher concentrations in hemp rather than in varieties of Cannabis cultivated for high tetrahydrocannabinol (THC) content and their corresponding psychoactive properties. The first batch was used as a vector in which was inserted a second copy of the gene of interest. Cannabis varieties exhibit one of three major cannabinoid profiles depending on the relative abundance of THCA and CBDA. THC, THCA, CBD, CBC, CBN: Medical Marijuana Composition, The Chemicals in Cannabis April 11, 2014 Medical Marijuana As the science of medical cannabis develops, we’re discovering more and more that breeding cannabis for different levels of medicinal compounds—known as cannabinoids—makes the medicine better for treating specific ailments . Each cannabinoid is produced at a different rate because they each have a different enzyme pathway. THCA synthase. In fact, marijuana flowers hardly contain any THC at all. Once heated, it morphs into THC. Δ1-Tetrahydrocannabinolic acid (THCA) synthase is the enzyme that catalyzes oxidative cyclization of cannabigerolic acid into THCA, Forensic Sci Int. , 2003; Pacifico et al. A positive result will cause the pink testing solution to turn yellow, which means the plant has either one or two copies of the active THCA allele. Recent evidence suggests that the genes encoding the two synthases are allelic (de Meijer et al. Each enzyme is recovered. Depending on their genome, the plants produce different amounts of two synthase enzymes that After re-watching this video, I've spotted quite a few rather embarrassing errors, so please don't be brutal if you find them, too. 1364 Taming THC: potential cannabis synergy and phytocannabinoid-terpenoid In most cannabis strains, CBG-A becomes CBDA or THCA immediately. These properties of CBDA synthase were similar to those of Δ 1-THCA synthase, which catalyzes the conversion of CBGA to Δ 1-THCA . kanabigerolat + O 2 ⇌ Delta9-tetrahidrokanabinolat + H 2 O 2. In order to investigate the structure–function relationship of THCA synthase, this enzyme was overproduced in insect cells, purified and finally crystallized in 0. CBD’s raw cannabinoid form, CBDa, and THC’s raw cannabinoid form, THCa, are synthase genes found on chromosome 6 of the 10 chromosomes of the cannabis genome. On the other hand, the first step THCA synthase catalyzes oxidative cyclization of the monoterpene moiety of CBGA to form THCA. Never miss a story from Kelly Rippel, when you sign up for Medium. Tetrahydrocannabinolic acid synthase (THCA synthase) and cannabidiolic acid synthase (CBDA synthase) catalyse the oxidative cyclization of cannabigerolic acid (CBGA), which results in the production of THCA and CBDA, respectively (Fig. plants. 0017 FIG. Figure 2). Specific residues of THCA synthase were identified by mutational analysis. Subsequent decarboxylation of THCA and CBDA via light exposure, heating, or aging, results in THC or CBD. THCA and THCV: Cannabinoids of the future 2017 could be the year of the medical cannabis gold rush. It was suggested that 1-Tetrahydrocannabinolic acid (THCA) synthase is a novel oxidoreductase that catalyzes the biosynthesis of the psychoactive compound THCA in Cannabis sativa (Mexican strain). Δ{sup 1}-Tetrahydrocannabinolic acid (THCA) synthase is a novel oxidoreductase that catalyzes the Generally, CBG and its precursor cannabigerolic acid (CBGa) do not stay around for long in hemp plants because they are very quick to combine with THCa synthase, CBDa synthase, or CBCa synthase to become THC, CBD, or CBC. Catalysis from CBGA to CBDA occurs through the same metabolic pathway as THCA, with the only difference being that there is another enzyme, THCA synthase, acting as a catalyst. New research from George Weiblen (University of Minnesota, USA) and colleagues has shown that in fact, THCA synthase and CBDA synthase are encoded by two separate but linked regions of the Cannabis genome. Abstract: (THCA) synthase. Raphael Mehoulam and Yechiel Gaoni in 1964 (from a piece of Lebanese hash) THCA – the acidic form of THC – is created from the action of the enzyme THCA synthase on the cannabinoid CBGA, which, as we already know, is the precursor of several compounds such as CBDA, CBCA or THCA itself. ferase, where THCA synthase is A-tetrahydrocannabinolic acid synthase, CBDA synthase is cannabidiolic acid syn thase, and CBCA synthase is cannabichromenic acid syn thase. July 23, 2014. Letting a solution of Terpene and THCA slowly evaporate can yield large singe crystals. Le cannabidiol (CBD) est un cannabinoïde présent dans le cannabis. There were two variants of the THCA synthase gene in the "drug-type" and "fiber-type" cannabis plants, respectively. Share. on. J Forensic Investigation 4(1): (2016) Page - 02 ISSN: 2330-0396 sequencing (NGS) results were examined, marijuana samples were identified that were apparent homozygotes for active or inactive The enzymes responsible for creating the cannabinoids with which most of us are familiar are cannabidiolic acid (CBDA) synthase, cannabichromenic acid (CBCA) synthase, and tetrahydrocannabinolic acid (THCA) synthase. THCA-A (CRM) (Item No. THCA is a non-psychoactive chemical found in raw cannabis. CBGA turns into CBDA with the help of the cannabis plant enzyme CBDA synthase. Patent Covering a Commercial Process for Biosynthetic Production of authentic THCA, CBDA and CBCA Cannabinoids News provided by Teewinot Life Sciences Simplistically it was assumed that this variation could all be traced back to differences in the two known cannabinoid synthase loci, THCA synthase and CBDA synthase, the former leading to high-THCA and the latter to low-THCA and higher CBDA content. On the other hand, some plants express genes that code for the enzyme CBDA synthase. tetrahydrocannabinolic acid synthase; THCA synthase; Delta1-tetrahydrocannabinolic acid synthase. For example, THCA is converted into THC and CBDA is converted into CBD. Il est présent dans trois médicaments : le Sativex, l'Epidiolex et le Cannador. THCA synthase and CBDA synthase convert CBGA to the carboxylated forms of THCA and CBDA, respectively, and share 89% nucleotide sequence identity (Sirikantaramas et al. 0. 1998), respectively. The transcriptome analysis showed that the THCA synthase gene, an essential enzyme in THCA production, is turned on in marijuana, but switched off in hemp," stated Page. 01) cannabinoid relative to the quantity formed of a second can CI2M I/40 (2006. CBGA-THCA synthase docking Crystallographic structures of the protein THCA synthase were Structure refinement and models evaluation retrieved from the RCSB database with PDB ID: The structural refinement of the THCA synthase models was 3VTE. Using a simple leaf punch, the test can detect whether the THCA synthase gene is present. Ovaj enzim je flavoprotein (FAD).

If a correlation existed, genetic analysis of the C. Based on data from 192 samples, we here propose the use of a set of two Single Nucleotide Polymorphisms (SNPs) found in two disparate regions of the cannabis genome; the mitochondria and the THCA synthase gene (**Table 1**). 1). medical cannabis is high in THCA content relative to CBDA due to high levels of THCA synthase No correlation existed between THCA synthase SNP profiles and THC concentration. ). Limonene synthase. (THCAS) converts CBGA to THCA, while CBDA synthase (CBDAS) forms CBDA and CBCA synthase (CBCAS) produces CBCA. It is produced by Δ(1-) Tetrahydrocannabinolic acid synthase (THCA) which catalyzes the oxidative cyclization of cannabigerolic acid (CBGA) the precursor of the THCA. 2014 Mar 3. Thirty-seven major substitutions were detected in the alignment of the …DNA polymorphisms in the tetrahydrocannabinolic acid (THCA) A portion of the THCA synthase gene was amplified by PCR with primers “g” and “h” that were designed in the present study The THCA and CBDA content in mature leaves of 13 C. Taura F, Morimoto S, Shoyama Y. , 2006). [10-12] Instead, THCA-Synthase acts as a Fiber-Optic Switching Mechanism to “harvest” Sunlight and place it into “reserves” (energy-storage proteins, edestin & albumin). 2004) and cannabichromenic acid synthase (Morimoto et al. , 2004 ). Five plants showed comparable levels of THCA and CBDA synthase expression, three plants showed higher CBDA than THCA expression, whereas two plants 9-tetrahydrocannabinolic acid (9-THCA) and cannabi-chromenic acid (CBCA; Morimoto et al. The final step differs, with THCA synthase and CBDA synthase producing THCA or CBDA, respectively, from CBGA. Today, it is widely accepted that marijuana has two main species The crop is easy to grow organically without using chemicals and is very pest resistant. THCA synthase converts the substrate CBGA into THCA and/or CBCA in a pH dependent manner in a bioreactor. THCA is the Hide 10 20 30 40 50. saliva strains was determined. That was a huge surprise—totally unexpected The enzymes that produce THCA or CBDA (THCA synthase and CBDA synthase, respectively) were believed to be two alleles of the same gene. THCA or tetrahydrocannabinolic acid, which is produced from enzyme THCA-synthase CBDA or cannabidiolic acid, produced by the action of enzyme CBDA-synthase CBCA or cannabichromenic acid, which is produced by enzyme CBCA-synthase Here we explore the potential role of copy number variation of THCA Synthase using phased single molecule sequencing and demonstrate that copy number and sequence variation of this gene is common and suggests a more nuanced view of chemotype prediction. Dr. THCA is synthesized in the trichomes of the cannabis flower when its precursor, CBGA (cannabigerolic acid), is exposed to an enzyme called THCA synthase. Specific residues of THCA …9/17/2004 · Abstract. The plant has natural enzymes, called synthases, that break the CBGA down and mold it toward the desired branch. Figure 3: Part of the cannabinoid biosynthetic pathway leading to the end products THC, CBD, and CBC. U. Furthermore, we identified a specific PCR marker for the THCA synthase gene for the "drug-type" strains. cannabinoid analogs by contacting a THCA synthase with a (51) Int. Pacifico et al.

Jan 23, 2017. 4. Cannabis plants make both THCA and CBDA from a common precursor called cannabigerolic acid (CBGA). THCA synthase is the first cannabinoid synthase to be studied and is potentially attractive target for various biotechnological applications as it produces the direct precursor of THC. Δ{sup 1}-Tetrahydrocannabinolic acid (THCA) synthase from C. 9% similar to THCA synthase in its 544-amino acid overlap, it should be possible to synthesize CBDA synthase in a similar fashion THCA synthase which has been synthesized multiple times (Sirikantaramas, 2004). 2004). Plants that produce high levels of THC express genes that code for the enzyme THCA synthase. e. LVYTQHDQLY MSILNSTIQN LRFISDTTPK Jul 30, 2005 Δ1-Tetrahydrocannabinolic acid (THCA) synthase is a novel oxidoreductase that catalyzes the biosynthesis of the psychoactive compound J Forensic Leg Med. 36 g THCA l-1) THCA could be produced by 10. , purification, molecular cloning, biochemical characterization, and possible biotechnological Although cannabinoid biosynthesis is not understood at the biochemical or genetic level, several key enzymes have been identified including a candidate polyketide synthase and the two oxidocyclases, THCA synthase (THCAS) and cannabidiolic acid (CBDA) synthase, which form the major cannabinoid acids [16 – 18]. The biosynthesis of the two principal cannabinoids of widespread interest, Δ-9-tetrahydrocannibinolic acid and cannabidiolic acid are the end products of a biosynthetic pathway in which cannabigerolic acid (CBG) serves as a precursor for both CBDA synthase and THCA synthase [3, 8,9]. 75 Å resolution. Once THCA or CBDA is heated or smoked, they decarboxylate to their neutral forms. FPP synthase. Pot Genome Sheds Light on Hemp Domestication Below: x Jump to "The transcriptome analysis showed that the THCA synthase gene, an essential enzyme in THCA production, is turned on in marijuana THCA synthase; Δ 1-tetrahydrocannabinolic acid synthase: Systematic name: cannabigerolate:oxygen oxidoreductase (cyclizing, Δ 9-tetrahydrocannabinolate-forming) Comments: A flavoprotein (FAD). It is produced by ∆1-Tetrahydrocannabinolic acid synthase (THCA) which catalyzes the oxidative cyclization of cannabigerolic acid (CBGA) the precursor of the THCA. An average half-life of CBD oil is around 24-48 hrs or about 1-2 days. Computational analysis was done to compute ligand checked for stability and energy minimization to avoid tetrahydrocannabinolic acid (THCA) and cannabidiolic acid (CBDA) (refer to Figure 2). 5 ). Therefore, THCA synthase is considered to be a key enzyme controlling cannabis psychoactivity. 4 years ago. The pharmacology of tetrahydrocannabinol (THC) is perhaps the most well studied of any scheduled substance, having well over 100 published clinical studies of medical cannabis and related products which contain THC (Ben Amar, 2006, Hazekamp and Grotenhermen, 2010, Kowal et al. Structure and function of 1-tetrahydrocannabinolic acid (THCA) synthase, the enzyme controlling the psychoactivity of Cannabis sativa. , 2008). As the cannabis flower matures, CBGA is converted to CBDA by the enzyme CBDA synthase, first discovered in 1996 by researchers in Japan. These plants are typically considered indica. 1 There are two acid isomers of Δ 9-THC (Item No. Crystallization of Delta1-tetrahydrocannabinolic acid (THCA) synthase from Cannabis sativa. 7, THCA sintaza, Delta1-tetrahidrokanabinolna kiselina sintaza) je enzim sa sistematskim imenom kanabigerolat:kiseonik oksidoreduktaza (ciklizacija, formira Delta9-tetrahidrokanabinolat). A mutation resulting in excess CBDA synthase or deficient THCA synthase would result in CBD-rich offspring. THCA-S stand for Tetrahydrocannabinolic Acid-Synthase. Oxidoreductases; Catalysing the reaction X-H + Y-H Tetrahydrocannabinolic acid (THCA) synthase is an enzyme responsible for catalyzing the formation of THCA from cannabigerolic acid (CBGA). Thirty-seven major substitutions were detected in the alignment of the deduced amino acid sequences from these variants. Here we explore the potential role of copy number variation of THCA Synthase using phased single molecule sequencing and demonstrate that copy number and sequence variation of this gene is common and suggests a more nuanced view of chemotype prediction. “At the end of the day, from our perspective, the plant is a wildly efficient way of producing complex compounds,” he says. In addition, Edman degradation of the purified enzyme revealed that CBDA synthase has an NH 2-terminal sequence similar to that of Δ 1-THCA synthase . S. the THCA synthase gene was successfully sequenced from twelve seized cannabis resin (Hashish) and four cannabis ‘‘fiber-type’’ plants. Then, as depicted in the second graphic below, THCa goes through the process of decarboxylation, losing a CO2 molecule and becoming THCv. youPCR THCA Marker Assay . As the extension primer for this SNP is a reverse primer a red labelled thymine is The Δ(9-)Tetrahydrocannabinol (THCA) is the primary psychoactive compound of Cannabis Sativa. Genotyping, quantitative trait locus (QTL) mapping, and gene expression assays associated genomic regions and loci with phenotypes to demonstrate that despite the linkage of separate loci for THCA synthase and CBDA synthase, it is variation at the Harry’s World: The Science Of CBDs. Analysis of THCA synthase gene expression in J Forensic Leg Med. Since the CBDA synthase is 83. A PCR marker Linked to a THCA synthase Polymorphism is a Reliable Tool to Discriminate Potentially THC-Rich Plants of Cannabis sativa L. Cannabigerol is one of the many phytocannabinoids within the cannabis plant, of which over 70 have been discovered and elucidated. CBD and The THCA synthase enzyme is a member of the p-cresol methyl-hydroxylase superfamily, and the tertiary structure is divided into two domains (domains I and II), with a flavin adenine dinucleotide coenzyme positioned between each domain and covalently bound to His114 and Cys176 (located in domain I). There, the enzyme genes are surrounded by vast swathes of garbled DNA which came from viruses that colonized the genome millions of years ago. on the loci relating to THCA. Published. Teewinot has developed patent-protected biosynthetic processes for the manufacture of THCVA, CBDVA, CBCVA, and CBGVA using enzymes such as THCA synthase and CBDA synthase. Purification and characterization of cannabidiolic-acid synthase from Cannabis sativa L. Why Cannabigerolic Acid (CBGa) is Kind of a Big Deal. J Forensic Investigation. THCA synthase might contribute to the self-defense of Cannabis plants by producing both THCA and hydrogen peroxide, but since these reaction products are toxic to the plant itself, THCA synthase must be secreted from secretory cells into the storage cavity to avoid cellular damage. it has been demonstrated that THCA is biosynthesized by an oxidoreductase named THCA synthase, which converts cannabigerolic acid (CBGA) into THCA, contrary to the generally postulated scheme that THCA is derived from cannabidiolic acid (8) (Figure 1). A schematic model of the THCA synthase (GenBank:JQ437482); α-helices are colored in cyan, β -strands are in red,and loops are in green. Author links open overlay panel Mareshige Kojoma a b Hikaru Seki b Shigeo Yoshida b Toshiya Muranaka b THCA is synthesized in the trichomes of the cannabis flower when its precursor, CBGA (cannabigerolic acid), is exposed to an enzyme called THCA synthase. Scientists that have studied the differences between indica and sativa have come up with a number of theories based on genetics. allowed the subsequent isolation of THCA synthase from an ancient cannabis sample from Xinjiang, and even the identification of a unique single nucleotide polymorphism (SNP) (Russo et al. In 2004, cDNA cloning of THCA synthase was achieved, allowing conversion of cannabigerolic acid (CBGA) to THC (Sirikantaramas et al. 01) nabinoid. Tetrahydrocannabinolic acid synthase. cannabinoids and flavonoids in Cannabis sativa L. For purification of the recombinant THCA synthase, a 1000-ml suspension culture of Sf9 cells (∼2. If there are any tests you are interested in that are not mentioned above However, rather than THCA synthase and CBDA synthase being allelic variants of the same locus, it has been proposed that they are linked loci 21, 25. Both genes are located within the sixth of cannabis' ten chromosomes, and both are surrounded by large Inactive enzyme unable to catalyze the production of delta 9-tetrahydrocannabinolate (THCA), Inactive tetrahydrocannabinolic acid synthase THCA synthase, a novel enzyme that catalyzes oxidative cyclization of CBGA, has been successfully purified from THCA strain. For example CBD and THC are both produced via the same metabolic pathway until the final step, where either CBDA synthase or THCA synthase metabolize the precursor molecule. The ∆9-Tetrahydrocannabinol (THCA) is the primary psychoactive compound of Cannabis Sativa. 4 M sodium citrate. We hope to track the similarities and differences reported between strains with similar cannabinoid ratios. Weights & Measures; - tests for relative levels of CBDA synthase to THCA synthase. THCA is found in variable quantities in fresh, undried cannabis, but is progressively decarboxylated to THC with drying, and especially under intense heating such as when cannabis is smoked or cooked into cannabis edibles. Class. CBGa folds upon itself into rings and makes THCa with using THCa- Synthase which is an enzyme. Whereas the product The structural and functional properties of CBDA synthase are quite similar to those of tetrahydrocannabinolic-acid (THCA) synthase, which is responsible for the biosynthesis of THCA, the major cannabinoid in drug-type Cannabis plants. youPCR THCA Marker Assay . Next, CBGA is cyclized into THCA, CBDA, or CBCA via the enzymes known as TCHA synthase, CBDA synthase, and CBCA synthase. 01) the reaction mixture to influence the quantity formed of a first CI2M I/34 (2006. LVYTQHDQLY MSILNSTIQN LRFISDTTPK 17 Sep 2004 Abstract. Various authors have tried using the secondary The enzymes making THC and CBD are encoded by THCA and CBDA synthase genes, respectively. zyme, v1-THCA synthase, has been puri¢ed to homogeneity and the N-terminal sequence has been reported [4]. THCA synthase is a 60 kDa (~500 amino acids) monomeric enzyme with the isoelectric point at 6. HO OH COOH. The '625 patent claims a biosynthetic process for manufacturing the cannabinoids THCA, CBDA and CBCA using THCA synthase and CBDA synthase. New discoveries have lead researchers to the hypothesis that it is the functionality of the enzyme, THCA synthase, not the absence of the gene coding for the enzyme that differentiates marijuana varieties from cannabis hemp varieties.
