Epi-isozizaene 5-monooxygenase (EC 1.14.13.106, CYP170A1) is an enzyme with systematic name (+)-epi-isozizaene,NADPH:oxygen oxidoreductase (5-hydroxylating). This enzyme catalyses the following chemical reaction

(+)-epi-isozizaene + 2 NADPH + 2 H + 2 O₂ ${\displaystyle \rightleftharpoons }$ albaflavenone + 2 NADP + 3 H₂O (overall reaction)

(1a) (+)-epi-isozizaene + NADPH + H + O₂ ${\displaystyle \rightleftharpoons }$ (5S)-albaflavenol + NADP + H₂O

(1b) (5S)-albaflavenol + NADPH + H + O₂ ${\displaystyle \rightleftharpoons }$ albaflavenone + NADP + 2 H₂O

(2a) (+)-epi-isozizaene + NADPH + H + O₂ ${\displaystyle \rightleftharpoons }$ (5R)-albaflavenol + NADP + H₂O

(2b) (5R)-albaflavenol + NADPH + H + O₂ ${\displaystyle \rightleftharpoons }$ albaflavenone + NADP + 2 H₂O

This cytochrome P450 enzyme is purified from bacterium Streptomyces coelicolor.
