WebAbstract. Cytochrome P450 is the name first given provisionally to describe a carbon monoxide-binding hemoprotein (Omura and Sato 1962), and for what has become recognized as a superfamily of monooxygenases found in just about every phylum in which the hemoprotein has been sought (Nelson et al. 1993). To date, more than 220 different … Cytochrome P450 enzymes also function to metabolize potentially toxic compounds, including drugs and products of endogenous metabolism such as bilirubin, principally in the liver. The Human Genome Project has identified 57 human genes coding for the various cytochrome P450 enzymes.
