CC -!- FUNCTION: Oxidoreductase involved in the biosynthesis of cannabinoids-
CC related terpenophenolic natural products, which have pharmacological
CC activity (PubMed:15190053, PubMed:17669365, Ref.4). Catalyzes the
CC oxidative cyclization of the monoterpene moiety in cannabigerolic acid
CC (CBGA), producing delta(9)-tetrahydrocannabinolate (THCA), the major
CC cannabioid in drug-type Cannabis plants (PubMed:15190053,
CC PubMed:17669365, Ref.4). Can also use cannabinerolic acid as substrate,
CC but not cannabigerol or cannabinerol (PubMed:15190053, PubMed:17669365,
CC Ref.4). {ECO:0000269|PubMed:15190053, ECO:0000269|PubMed:17669365,
CC ECO:0000269|Ref.4}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=cannabigerolate + O2 = Delta(9)-tetrahydrocannabinolate +
CC H2O2; Xref=Rhea:RHEA:34135, ChEBI:CHEBI:15379, ChEBI:CHEBI:16240,

CC -!- COFACTOR:
CC Name=FAD; Xref=ChEBI:CHEBI:57692;
CC Evidence={ECO:0000269|PubMed:22766313};
CC Note=Binds 1 FAD per subunit in a bicovalent manner.
CC {ECO:0000269|PubMed:22766313};
CC -!- ACTIVITY REGULATION: Inhibited by Hg(2+). {ECO:0000269|Ref.4}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC Kinetic parameters:
CC KM=134 uM for cannabigerolic acid {ECO:0000269|PubMed:15190053,
CC ECO:0000269|Ref.4};
CC KM=254 uM for cannabinerolic acid {ECO:0000269|PubMed:15190053,
CC ECO:0000269|Ref.4};
CC Vmax=2.68 nmol/sec/mg enzyme with cannabigerolic acid as substrate
CC {ECO:0000269|PubMed:15190053, ECO:0000269|Ref.4};
CC Vmax=0.37 nmol/sec/mg enzyme with cannabinerolic acid as substrate
CC {ECO:0000269|PubMed:15190053, ECO:0000269|Ref.4};
CC Note=kcat is 0.30 sec(-1) for cannabigerolate.;
CC pH dependence:
CC Optimum pH is 5.5-6.0. {ECO:0000269|PubMed:15190053,
CC ECO:0000269|Ref.4};
CC -!- PATHWAY: Secondary metabolite biosynthesis; terpenoid biosynthesis.
CC {ECO:0000303|PubMed:30468448}.
CC -!- SUBUNIT: Monomer. {ECO:0000269|PubMed:22766313, ECO:0000269|Ref.4}.
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:16024552}. Secreted,
CC extracellular space, apoplast {ECO:0000269|PubMed:16024552}.
CC Note=Sorted from the secretory cells into the storage cavity of
CC glandular trichomes. {ECO:0000269|PubMed:16024552}.
CC -!- TISSUE SPECIFICITY: Expressed in the secretory cells of glandular
CC trichomes. {ECO:0000269|PubMed:16024552}.
CC -!- PTM: Glycosylated when produced in a heterologous system. The
CC deglycosylated THCA synthase has more catalytic activity than the
CC glycosylated form. {ECO:0000269|PubMed:15190053,
CC ECO:0000269|PubMed:17669365}.
CC -!- PTM: The FAD cofactor is bound via a bicovalent 6-S-cysteinyl, 8alpha-
CC N1-histidyl FAD linkage. {ECO:0000269|PubMed:22766313}.
CC -!- POLYMORPHISM: Several isoforms of the active tetrahydrocannabinolic
CC acid synthase found in the 'drug-type' cannabis plants exist due to
CC polymorphism. {ECO:0000269|PubMed:16143478}.
CC -!- MISCELLANEOUS: THCA synthase might contribute to the self-defense of
CC Cannabis plants by producing both THCA and hydrogen peroxide, but since
CC these reaction products are toxic to the plant itself, THCA synthase
CC must be secreted from secretory cells into the storage cavity to avoid
CC cellular damage.
CC -!- SIMILARITY: Belongs to the oxygen-dependent FAD-linked oxidoreductase
CC family. {ECO:0000305}.
