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   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC         Evidence={ECO:0000250|UniProtKB:A0A1C9J6A7};

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}.
