RT "Identification of novel sesquiterpene synthase genes that mediate the
RT biosynthesis of valerianol, which was an unknown ingredient of tea.";
RL Sci. Rep. 8:12474-12474(2018).
CC -!- FUNCTION: Terpene synthase that catalyzes the biosynthesis of the
CC terpene valerianol, which is a volatile compound of floral scent.
CC {ECO:0000269|PubMed:30127518}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=(2E,6E)-farnesyl diphosphate + H2O = diphosphate + valerianol;
CC Xref=Rhea:RHEA:60424, ChEBI:CHEBI:15377, ChEBI:CHEBI:33019,
CC ChEBI:CHEBI:143779, ChEBI:CHEBI:175763; EC=4.2.3.204;
CC Evidence={ECO:0000269|PubMed:30127518};
CC PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:60425;
CC Evidence={ECO:0000269|PubMed:30127518};
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: Secondary metabolite biosynthesis; terpenoid biosynthesis.
CC {ECO:0000305}.
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. {ECO:0000305}.
