Biflaviolin synthase (EC 1.14.21.7, CYP158A2, CYP 158A2, cytochrome P450 158A2) is an enzyme with systematic name flaviolin,NADPH:oxygen oxidoreductase.[1][2][3] This enzyme catalyses the following chemical reaction

(1) 2 flaviolin + NADPH + H+ + O2 [math]\displaystyle{ \rightleftharpoons }[/math] 3,3'-biflaviolin + NADP+ + 2 H2O
(2) 2 flaviolin + NADPH + H+ + O2 [math]\displaystyle{ \rightleftharpoons }[/math] 3,8'-biflaviolin + NADP+ + 2 H2O

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