Cytochrome P450

Cytochrome P450 (CYP450) enzymes are a diverse group of catalysts that contains 57 members in humans. CYPs are usually membrane-bound and are localized to the inner mitochondrial or endoplasmic reticular membrane. CYPs have oxygenase activity.

Cytochrome P450 (CYP450) enzymes are a diverse group of catalysts that contains 57 members in humans. CYPs are usually membrane-bound and are localized to the inner mitochondrial or endoplasmic reticular membrane. CYPs have oxygenase activity and commonly catalyze redox reactions, involving the oxidation of the substrate and reduction of water. This group of enzymes contain a heme iron within the active site, which is essential for catalytic activity.

CYPs have been found in all organisms tested and are ubiquitously expressed. They are found at high levels in the liver, where they have an important role in metabolism of drugs and endogenous toxic compounds (for example bilirubin). Most CYPs can metabolize numerous substrates and this accounts for their major role in drug interactions. CYPs also have functions in steroid hormone synthesis, cholesterol synthesis and vitamin D metabolism.
