CC -!- FUNCTION: Monoterpene synthase involved in the biosynthesis of volatile
CC compounds widely used in aromatherapy and folk medicine, and present in
CC culinary herbs (PubMed:24943828). Mediates the conversion of (2E)-
CC geranyl diphosphate (GPP) into alpha-pinene and, as minor compounds,
CC into alpha-phellandrene, limonene and alpha-terpinolene
CC (PubMed:24943828). {ECO:0000269|PubMed:24943828}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2E)-geranyl diphosphate = alpha-pinene + diphosphate;
CC Xref=Rhea:RHEA:25662, ChEBI:CHEBI:33019, ChEBI:CHEBI:36740,
CC ChEBI:CHEBI:58057; Evidence={ECO:0000269|PubMed:24943828};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:25663;
CC Evidence={ECO:0000269|PubMed:24943828};
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|PubMed:24943828}.
CC -!- SUBCELLULAR LOCATION: Plastid, chloroplast {ECO:0000255}.
CC -!- TISSUE SPECIFICITY: Expressed at low levels in leaves.
CC {ECO:0000269|PubMed:24943828}.
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}.
