In this review article the properties of cytochrome P450 BM3 (CYB 102 E.C. 1.14.14.1) and nitric oxide synthase (E.C. 1.14.13.39) have been considered. These enzymes are catalytically self-safficient P450-like systems, with flavins (FAD and FMN) and heme on one polypeptide molecule. Two- and three component cytochrome P450 systems have flavins and heme on the different protein molecules The rates of substrate metabolism catalyzed by monocomponent cytochrome P450 BM3 and nitric oxide synthase are substantially higher in comparison with two- and three-component P450 monooxygenase system. In this manuscripte authors have been discussed the properties of semisynthetic flavocytochromes based on cytochrome P450 2B4. with monooxygenase and reductase activities. These semi-artificial flavocytochromes obtained by authors serve as structural models of one-component systems and have the functional properties of two-component system (microsomal monooxygenase system).
