CC -!- FUNCTION: TS is a member of the terpene cyclase group of enzymes. It
CC catalyzes the isomerization and cyclization of farnesyl pyro-phosphate
CC to form trichodiene, the first cyclic intermediate in the biosynthetic
CC pathway for trichothecenes. It serves to branch trichothecene
CC biosynthesis from the isoprenoid pathway.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2E,6E)-farnesyl diphosphate = diphosphate + trichodiene;
CC Xref=Rhea:RHEA:12052, ChEBI:CHEBI:15861, ChEBI:CHEBI:33019,
CC ChEBI:CHEBI:175763; EC=4.2.3.6;
CC -!- PATHWAY: Sesquiterpene biosynthesis; trichothecene biosynthesis.
CC -!- MISCELLANEOUS: Trichothecenes are sesquiterpenoid toxins that act by
CC inhibiting protein biosynthesis.
CC -!- SIMILARITY: Belongs to the trichodiene synthase family. {ECO:0000305}.
