CC   -!- FUNCTION: Catalyzes the cyclization of farnesyl diphosphate to alpha-
CC       copaene and (+)-delta cadinene. {ECO:0000269|PubMed:22459969}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2E,6E)-farnesyl diphosphate = (1S,8aR)-delta-cadinene +
CC         diphosphate; Xref=Rhea:RHEA:19525, ChEBI:CHEBI:15385,
CC         ChEBI:CHEBI:33019, ChEBI:CHEBI:175763; EC=4.2.3.13;
CC         Evidence={ECO:0000269|PubMed:22459969};
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=(2E,6E)-farnesyl diphosphate = alpha-copaene + diphosphate;
CC         Xref=Rhea:RHEA:33991, ChEBI:CHEBI:10221, ChEBI:CHEBI:33019,
CC         ChEBI:CHEBI:175763; EC=4.2.3.133;
CC         Evidence={ECO:0000269|PubMed:22459969};
CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC       Note=Binds 3 Mg(2+) ions per subunit. {ECO:0000250};
CC   -!- DOMAIN: The Asp-Asp-Xaa-Xaa-Asp/Glu (DDXXD/E) motif is important for
CC       the catalytic activity, presumably through binding to Mg(2+).
CC       {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the terpene synthase family. {ECO:0000305}.
