CC -!- FUNCTION: Terpene synthase that catalyzes the conversion of (2E,6E)-
CC farnesyl diphosphate (FPP) into sesquiterpenes which are important for
CC fungi-environment interactions (PubMed:31239482). Produces a mixture
CC consisting of 8 sesquiterpenes including corvol ethers A and B, as well
CC as traces of epizonarene, gamma-cadinene, delta-cadinene, alpha-
CC cadinene, alpha-cadinol, and an unidentified sesquiterpene
CC (PubMed:31239482). The major product is corvol ether A
CC (PubMed:31239482). {ECO:0000269|PubMed:31239482}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2E,6E)-farnesyl diphosphate + H2O = (+)-corvol ether B +
CC diphosphate; Xref=Rhea:RHEA:53644, ChEBI:CHEBI:15377,
CC ChEBI:CHEBI:33019, ChEBI:CHEBI:137536, ChEBI:CHEBI:175763;

CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2E,6E)-farnesyl diphosphate + H2O = (+)-corvol ether A +
CC diphosphate; Xref=Rhea:RHEA:53648, ChEBI:CHEBI:15377,

CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:53649;
CC Evidence={ECO:0000269|PubMed:31239482};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:B5HDJ6};
CC Note=Binds 3 Mg(2+) ions per subunit. {ECO:0000250|UniProtKB:B5HDJ6};
CC -!- DOMAIN: The Asp-Asp-Xaa-Xaa-Xaa-Asp (DDXXXD) motif is important for the
CC catalytic activity, presumably through binding to Mg(2+).
CC {ECO:0000250|UniProtKB:B5HDJ6}.
CC -!- SIMILARITY: Belongs to the terpene synthase family. {ECO:0000305}.
