Epi-isozizaene 5-monooxygenase (EC 1.14.15.39, CYP170A1) is an enzyme with systematic name (+)-epi-isozizaene,NADPH:oxygen oxidoreductase (5-hydroxylating).[1] This enzyme catalyses the following overall chemical reaction:

+ 4 reduced
ferredoxin
 
 
2 O2
3 H2O

+ 4 oxidised
ferredoxin
 

The enzyme from Streptomyces coelicolor is an oxidoreductase which uses molecular oxygen to insert a hydroxy group into (+)-epi-isozizaene and then further oxidises that intermediate to the ketone product. It requires ferredoxin to transfer electrons to the cytochrome P450 active site.[2]
