Comments
Comment typeDescription
Biophysicochemical PropertiesKinetic parameters: Vmax=1.7 pmol/sec/mg enzyme toward geranyl diphosphate {ECO:0000269|PubMed:12566586};
Catalytic ActivityGeranyl diphosphate = myrcene + diphosphate.
CofactorName=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250}; Name=Mn(2+); Xref=ChEBI:CHEBI:29035; Evidence={ECO:0000250}; Note=Binds 3 Mg(2+) or Mn(2+) ions per subunit. {ECO:0000250};
DomainThe Asp-Asp-Xaa-Xaa-Asp/Glu (DDXXD/E) motif is important for the catalytic activity, presumably through binding to Mg(2+).
FunctionInvolved in monoterpene (C10) biosynthesis. The major products are alpha- and beta-pinene, sabinene, beta-myrcene, (E)- beta-ocimene and limonene. {ECO:0000269|PubMed:12566586}.
PathwaySecondary metabolite biosynthesis; terpenoid biosynthesis.
SimilarityBelongs to the terpene synthase family. Tpsb subfamily. {ECO:0000305}.
Subcellular LocationPlastid, chloroplast {ECO:0000305}.
Tissue SpecificityExpressed exclusively in mature flowers, but not in inmmature buds. {ECO:0000269|PubMed:12566586}.
