Protein
Germacrene A hydroxylase
Gene
GAO
Organism
Saussurea costus (Costus) (Aucklandia costus)
Status
Functioni
Involved in the biosynthesis of germacrene-derived sesquiterpene lactones (PubMed:20351109). Catalyzes three consecutive oxidations of germacrene A to produce germacrene A acid (PubMed:20351109). Could also catalyze the three-step oxidation of non-natural substrate amorphadiene to artemisinic acid (PubMed:20351109).1 Publication
Catalytic activityi
- (+)-(R)-germacrene A + 3 O2 + 3 reduced [NADPH—hemoprotein reductase] = germacra-1(10),4,11(13)-trien-12-oate + 4 H+ + 4 H2O + 3 oxidized [NADPH—hemoprotein reductase]1 PublicationEC:1.14.14.951 PublicationThis reaction proceeds in the forward1 Publication direction.
