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. 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 ...

Animals often have more CYP genes than do humans. Reported numbers range from 35 genes in the sponge Amphimedon queenslandica to 235 genes in the cephalochordate Branchiostoma floridae. Mice have genes for 101 CYPs, and sea urchins have even more (perhaps as many as 120 genes).
