CC -!- FUNCTION: Monoterpene synthase (TPS) involved in the biosynthesis of
CC monoterpene natural products included in conifer oleoresin secretions
CC and volatile emissions; these compounds contribute to biotic and
CC abiotic stress defense against herbivores and pathogens
CC (PubMed:23679205). Catalyzes the conversion of (2E)-geranyl diphosphate
CC (GPP) to (+)-alpha-pinene (PubMed:23679205).
CC {ECO:0000269|PubMed:23679205}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2E)-geranyl diphosphate = (1R,5R)-alpha-pinene + diphosphate;
CC Xref=Rhea:RHEA:32575, ChEBI:CHEBI:28261, ChEBI:CHEBI:33019,
CC ChEBI:CHEBI:58057; EC=4.2.3.121;
CC Evidence={ECO:0000269|PubMed:23679205};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:32576;
CC Evidence={ECO:0000269|PubMed:23679205};
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: Terpene metabolism; oleoresin biosynthesis.
CC {ECO:0000269|PubMed:23679205}.
CC -!- PATHWAY: Secondary metabolite biosynthesis; terpenoid biosynthesis.
CC {ECO:0000269|PubMed:23679205}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000255}.
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:0000305}.
CC -!- SIMILARITY: Belongs to the terpene synthase family. Tpsd subfamily.
CC {ECO:0000305}.
