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}.
