A variant of P450 BM3 with an F87V substitution [P450 BM3 (F87V)] is a substrate-promiscuous cytochrome P450 monooxygenase. We investigated the bioconversion of various flavonoids (favanones, chalcone, and isoflavone) by using recombinant Escherichia coli cells, which expressed the gene coding for P450 BM3 (F87V), to give their corresponding hydroxylated products. Potent antioxidative activities were observed in some of the products.
