RT "Evolution of conifer diterpene synthases: diterpene resin acid
RT biosynthesis in lodgepole pine and jack pine involves monofunctional and
RT bifunctional diterpene synthases.";
RL Plant Physiol. 161:600-616(2013).
CC -!- FUNCTION: Involved in defensive oleoresin formation in conifers in
CC response to insect attack or other injury. Involved in diterpene (C20)
CC olefins biosynthesis. Monofunctional enzyme lacking the DXDD motif in
CC the class II active site relevant for the cyclization of geranylgeranyl
CC diphosphate (GGPP). Requires (+)-copalyl diphosphate ((+)-CPP) as
CC substrate, but no activity with GGPP or ent-CPP. Pimaradiene is the
CC major products of the enzyme. {ECO:0000269|PubMed:23370714}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(+)-copalyl diphosphate = diphosphate + pimara-8(14),15-diene;
CC Xref=Rhea:RHEA:42984, ChEBI:CHEBI:8210, ChEBI:CHEBI:33019,
CC ChEBI:CHEBI:58635; EC=4.2.3.147;
CC Evidence={ECO:0000269|PubMed:23370714};
CC -!- COFACTOR:
CC Name=Mg(2+); Xref=ChEBI:CHEBI:18420;
CC Evidence={ECO:0000250|UniProtKB:Q40577};
CC Note=Binds 3 Mg(2+) ions per subunit. {ECO:0000250|UniProtKB:Q40577};
CC -!- PATHWAY: Terpene metabolism; oleoresin biosynthesis. {ECO:0000305}.
CC -!- MISCELLANEOUS: The Asp-Asp-Xaa-Xaa-Asp/Glu (DDXXD/E) motif important
CC for the catalytic activity in the class I active site is degenetated,
CC but the Mg(2+) binding sites are conserved. {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the terpene synthase family. Tpsd subfamily.
CC {ECO:0000305}.
