1.14.13.106
Accepted name
epi-isozizaene 5-monooxygenase
Reaction
(+)-epi-isozizaene + 2 NADPH + 2 H+ + 2 O2 = albaflavenone + 2 NADP+ + 3 H2O (overall reaction);;(1a) (+)-epi-isozizaene + NADPH + H+ + O2 = (5S)-albaflavenol + NADP+ + H2O;;(1b) (5S)-albaflavenol + NADPH + H+ + O2 = albaflavenone + NADP+ + 2 H2O;;(2a) (+)-epi-isozizaene + NADPH + H+ + O2 = (5R)-albaflavenol + NADP+ + H2O;;(2b) (5R)-albaflavenol + NADPH + H+ + O2 = albaflavenone + NADP+ + 2 H2O
Other name(s)
CYP170A1
Systematic name
(+)-epi-isozizaene,NADPH:oxygen oxidoreductase (5-hydroxylating)
CAS registry number
1207718-51-1
Comment
This cytochrome-P-450 enzyme, from the soil-dwelling bacterium Streptomyces coelicolor A3(2), catalyses two sequential allylic oxidation reactions. The substrate epi-isozizaene, which is formed by the action of EC 4.2.3.37, epi-isozizaene synthase, is first oxidized to yield the epimeric intermediates (5R)-albaflavenol and (5S)-albaflavenol, which can be further oxidized to yield the sesquiterpenoid antibiotic albaflavenone.
