Biotransformations using prokaryotic P450 monooxygenases

Recent studies on microbial cytochrome P450 enzymes have covered several new areas. Advances have been made in structure-function analysis and new nonenzymatic/electrochemical systems for the replacement of NAD(P)H in biocatalysis have been developed. Furthermore, the properties of some enzymes have been re-engineered by site-directed mutagenesis or by methods of directed evolution and new P450s have been functionally expressed and characterized. It is thought that a combination of these approaches will facilitate the use of isolated P450 monooxygenases in biocatalysis.
