Biflaviolin synthase

Biflaviolin synthase (, CYP158A2, CYP 158A2, cytochrome P450 158A2) is an enzyme with systematic name flaviolin,NADPH:oxygen oxidoreductase. This enzyme catalyses the following chemical reaction

(1) 2 flaviolin + 2 reduced ferridoxin + 2 H<sup>+</sup> + O<sub>2</sub> 3,3'-biflaviolin + 2 oxidised ferridoxin+ 2 H<sub>2</sub>O
(2) 2 flaviolin + 2 reduced ferridoxin + 2 H<sup>+</sup> + O<sub>2</sub> 3,8'-biflaviolin + 2 oxidised ferridoxin + 2 H<sub>2</sub>O

This cytochrome P450 enzyme, from the soil-dwelling bacterium Streptomyces coelicolor A3(2), catalyses a phenol oxidation C-C coupling reaction.
