Isoflavonoids are a class of polycyclic aromatic hydrocarbon compounds originating from plants as secondary metabolites. Their oxidative metabolites such as ortho dihydroxyisoflavones (ODIs), where the ortho carbons of the hydroxyl groups are hydroxylated, have been reported to have a remarkably high antioxidant effect. Here, we report enzyme engineering of the cytochrome P450 enzyme CYP102A1 (BM3) for the synthesis of ODIs from isoflavonoids.
