There are 18 mammalian cytochrome p450 (cyp) families, which encode 57 genes in the human genomecyp2, cyp3 and cyp4 families contain far more genes than the other 15 families these three families are also the ones that are dramatically larger in rodent genomes. Cytochromes p450 are a group of heme-thiolate monooxygenases in liver microsomes, this enzyme is involved in an nadph-dependent electron transport pathway. The iuphar/bps guide to pharmacology cyp3a4 - cyp3 family detailed annotation on the structure, function, physiology, pharmacology and clinical relevance of drug targets. Cytochrome p450 (cyp) is a membrane bound protein present in most tissues in the body it is a member of a superfamily of proteins known as hemoproteins – those that contain a heme group that is active in the catalytic mechanism of these various proteins other members of this family in humans.

Metabolizes several precarcinogens, drugs, and solvents to reactive metabolites inactivates a number of drugs and xenobiotics and also bioactivates many xenobiotic substrates to their hepatotoxic or carcinogenic forms. Cytochrome p450 effects a more significant issue when it comes to drug/drug interactions is the issue that arises from the inhibition or induction of the cyp450 hepatic microsomal enzyme system.
