We had reported engineering of the heme monooxygenase cytochrome P450cam from Pseudomonas putida with the F87W/Y96F/L244A/V247L mutations for the oxidation of pentachlorobenzene (PeCB), a recalcitrant environmental contaminant, to pentachlorophenol. In order to provide further insights into P450 structure, function and
