cytochrome P450 (CYP) superfamily; Cytochrome P450 (P450, CYP) is a large superfamily of heme-containing proteins that catalyze a variety of oxidative reactions of a large number of structurally different endogenous and exogenous compounds in organisms from all major domains of life. CYPs with > 40% sequence identity are members of the same family. There are approximately 2250 CYP families: mammals, insects, plants, fungi, bacteria, and archaea have around 18, 208, 277, 805, 591, and 14 families, respectively. CYPs bind their diverse ligands in a buried, hydrophobic active site, which is accessed through a substrate access channel formed by two flexible helices and their connecting loop. Their monooxygenase activity relies on the reductive scission of molecular oxygen bound to the P450 heme iron, and the delivery of two electrons to the heme iron during the catalytic cycle. CYPs use a variety of redox partners, such as the eukaryotic diflavin enzyme NADPH-cytochrome P450 oxidoreductase and the bacterial/mitochondrial NAD(P)H-ferredoxin reductase and ferredoxin partners. Some CYPs are naturally linked to their redox partners and others have evolved to bypass requirements for redox partners, and instead react directly with hydrogen peroxide or NAD(P)H to facilitate oxidative or reductive catalysis.

The CYP4A, CYP4X, and CYP4Z subfamilies are specific to mammals, CYP4T is present in fish, while CYP4B is conserved among vertebrates. CYP4As are known for catalyzing arachidonic acid to 20-HETE (20-hydroxy-5Z,8Z,11Z,14Z-eicosatetraenoic acid), and some can also metabolize lauric and palmitic acid. CYP4Bs specialize in omega-hydroxylation of short chain fatty acids and also participates in the metabolism of exogenous compounds that are protoxic including valproic acid (C8), 3-methylindole (C9), 4-ipomeanol, 3-methoxy-4-aminoazobenzene, and several aromatic amines. CYP4X1 is expressed at high levels in the mammalian brain and may play a role in regulating fat metabolism. CYP4Z1 is a fatty acid hydroxylase that is unique among human CYPs in that it is predominantly expressed in the mammary gland. Monophyly was not found with the CYP4T and CYP4B subfamilies, and further consideration should be given to their nomenclature.

Cytochrome P450; Cytochrome P450s are haem-thiolate proteins involved in the oxidative degradation of various compounds. They are particularly well known for their role in the degradation of environmental toxins and mutagens. They can be divided into 4 classes, according to the method by which electrons from NAD(P)H are delivered to the catalytic site. Sequence conservation is relatively low within the family - there are only 3 absolutely conserved residues - but their general topography and structural fold are highly conserved. The conserved core is composed of a coil termed the 'meander', a four-helix bundle, helices J and K, and two sets of beta-sheets. These constitute the haem-binding loop (with an absolutely conserved cysteine that serves as the 5th ligand for the haem iron), the proton-transfer groove and the absolutely conserved EXXR motif in helix K. While prokaryotic P450s are soluble proteins, most eukaryotic P450s are associated with microsomal membranes. their general enzymatic function is to catalyze regiospecific and stereospecific oxidation of non-activated hydrocarbons at physiological temperatures.
