studies on the characterization of fattyacid hydroxylases. Three novel potential fattyacid hydroxylases (CYP109D1, CYP264A1, and CYP266A1) were used for detailed characterization. One of them, CYP109D1 was able to perform subterminal hydroxylation of saturated fattyacids with the support of two autologous and one heterologous electron transfer system(s). The kinetic parameters for the product hydroxylation
Cytochrome P450 BM-3 (EC 1.14.14.1) is a monooxygenase that utilizes NADPH and dioxygen to hydroxylate fatty acids at subterminal positions. The enzyme is also capable of functioning as a peroxygenase in the same reaction, by utilizing hydrogen peroxide in place of the reductase domain, cofactor and oxygen. As a starting point for developing a practically useful hydroxylation biocatalyst, we compare the activity and regioselectivity of wild-type P450 BM-3 and its F87A mutant on various fatty acids. Neither enzyme catalyzes terminal hydroxylation under any of the conditions studied. While significantly enhancing peroxygenase activity, the F87A mutation also shifts hydroxylation further away from the terminal position. The H2O2-driven reactions with either the full-length BM-3 enzyme or the heme domain are slow, but yield product distributions very similar to those generated when using NADPH and O-2.
