Diclofenac is a nonsteroidal anti-inflammatory drug. It undergoes hydroxylation by mammalian cytochrome P450 enzymes at 4'- and/or 5'-positions. A bacterial P450 enzyme, CYP105D7 from Streptomyces avermitilis, has been shown to catalyze hydroxylation of 1-deoxypentalenic acid and an isoflavone daidzein. Here
