WebFeb 6, 2004 · Cytochrome P450cam Compound I Kinetic characterization Peroxide shunt Peroxide reaction Cytochromes P450 (P450s) form a ubiquitous and large superfamily of hemeprotein monooxygenases that metabolize physiologically important compounds vital to life of most organisms from protists to plants to mammals [1], [2]. WebNative, camphor-free P450 cam contains low-spin ferric iron, part of which (approx. 50-70%) is converted to the high-spin ferric state upon addition of camphor. The Mössbauer spectra of the camphor-free enzyme (S = 1 2) and of the high-spin component (S = 5 2) of the camphor complex have been successfully simulated using a model based on ...
WebCytochrome P450 CAM with a known X-ray structure and well-studied oxygenase reaction cycle, has been studied for its ability to reduce carbon-halogen bonds under anaerobic conditions. The reductive reactions functioned with NADH and the physiological electron-transfer proteins or by using artificial electron donors to reduce cytochrome P450 CAM.
