S. Blot,D. Koulenti,G. Dimopoulos. Cytochrome P450 is known to catalyze hydroxylations, epoxidations, .-, .-, and .-dealkylations, .-oxidations, sulfoxidations, dehalogenations, and other reactions.. The reactive site of all of these enzymes is extraordinarily simple, containing only an iron protoporphyrin IX (.) (Fig. 1) with cyst

M. Carlier,V. Stove,J. J. De Waele between peroxidases and P450s include the ability of P450s to accept electrons from a reductase; the redox potentials of the higher oxidation states; and the ability of P450s to generate the equivalent of a metal-bound peroxide by reduction of O. at the heme center during catalytic turnover.

Thus, scientists have become interested in the mechanisms of disease states resulting from mutations in P450s, and in alternative substrates metabolized and new products formed by the engineering of known P450 proteins. Only through an understanding of the structures of these p

Kellumme-thiolate proteins, the cytochromes P450 responsible for monooxygenation reactions (which will be called “classical P450s” in this chapter) have been extensively studied. and their mechanisms of dioxygen activation and substrate hydroxylation are now well established..
