CYP199A2, a bacterial P450 monooxygenase from Rhodopseudomonas palustris, was found to exhibit oxidation activity towards three hydroxynaphthoic acids. Whole cells of the recombinant Escherichia coli strain expressing CYP199A2 efficiently catalyzed the regioselective oxidation of 1-, 3-, and 6-hydroxy-2-naphthoic acids to produce 1,7-, 3,7-, and 6,7-dihydroxynaphthoic acid respectively. These results suggest that CYP199A2 might be a useful oxidation biocatalyst for the synthesis of dihydroxynaphthoic acids.
