BRITE hierarchy
Sysname
amorpha-4,11-diene,NADPH:oxygen oxidoreductase (12-hydroxylating)
Reaction(IUBMB)
amorpha-4,11-diene + 3 O2 + 3 NADPH + 3 H+ = artemisinate + 3 NADP+ + 4 H2O (overall reaction) [RN:R10026];
(1a) amorpha-4,11-diene + O2 + NADPH + H+ = artemisinic alcohol + NADP+ + H2O [RN:R10023];
(1b) artemisinic alcohol + O2 + NADPH + H+ = artemisinic aldehyde + NADP+ + 2 H2O [RN:R10024];
(1c) artemisinic aldehyde + O2 + NADPH + H+ = artemisinate + NADP+ + H2O [RN:R10025]
