RT gene from Eleutherococcus trifoliatus.";

CC -!- FUNCTION: Sesquiterpene synthase involved in the biosynthesis of
CC volatile compounds (Ref.1). Mediates the conversion of (2E,6E)-farnesyl
CC diphosphate (FPP) into alpha-copaene (Ref.1). Not active with geranyl
CC diphosphate (GPP) as substrate (Ref.1). {ECO:0000269|Ref.1}.
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; Evidence={ECO:0000269|Ref.1};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:33992;
CC Evidence={ECO:0000269|Ref.1};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:A0A1C9J6A7};
CC Name=Mn(2+); Xref=ChEBI:CHEBI:29035;
CC Evidence={ECO:0000250|UniProtKB:A0A1C9J6A7};
CC Note=Binds 3 Mg(2+) or Mn(2+) ions per subunit.
CC {ECO:0000250|UniProtKB:A0A1C9J6A7};
CC -!- PATHWAY: Secondary metabolite biosynthesis; terpenoid biosynthesis.
CC {ECO:0000269|Ref.1}.
CC -!- TISSUE SPECIFICITY: Expressed in stems and leaves and, at low levels,
CC in rrots. {ECO:0000269|Ref.1}.
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|UniProtKB:Q40577}.
CC -!- SIMILARITY: Belongs to the terpene synthase family. Tpsa subfamily.
CC {ECO:0000305}.
