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.

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.

However, there is a phenomenon called family creep, where a sequence (below 40% identity) is absorbed into a large family; this is seen in the plant CYP71 and CYP89 families. The plant CYPs have also been classified according to clans; land plants have 11 clans that form two groups: single-family clans (CYP51, CYP74, CYP97, CYP710, CYP711, CYP727, CYP746) and multi-family clans (CYP71, CYP72, CYP85, CYP86).

cytochrome P450 family 1; The cytochrome P450 family 1 (CYP1 or Cyp1) is composed of three functional human members: CYP1A1, CYP1A2 and CYP1B1, which are regulated by the aryl hydrocarbon receptor (AhR), ligand-activated transcriptional factor that dimerizes with AhR nuclear translocator (ARNT). CYP1 enzymes are involved in the metabolism of endogenous hormones, xenobiotics, and drugs. Included in the CYP1 family is CYP1D1 (cytochrome P450 family 1, subfamily D, polypeptide 1), which is not expressed in humans as its gene is pseudogenized due to five nonsense mutations in the putative coding region, but is functional in in other organisms including cynomolgus monkey. Zebrafish CYP1D1 expression is not regulated by AhR. The CYP1 family belongs to the large cytochrome P450 (P450, CYP) 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 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.

cytochrome P450 21, also called steroid 21-hydroxylase; Cytochrome P450 21 (CYP21 or Cyp21), also called steroid 21-hydroxylase (EC 1.14.14.16) or cytochrome P-450c21 or CYP21A2 (in humans), catalyzes the 21-hydroxylation of steroids such as progesterone and 17-alpha-hydroxyprogesterone (17-alpha-OH-progesterone) to form 11-deoxycorticosterone and 11-deoxycortisol, respectively. It is required for the adrenal synthesis of mineralocorticoids and glucocorticoids. Deficiency of this CYP is involved in ~95% of cases of human congenital adrenal hyperplasia, a disorder of adrenal steroidogenesis. There are two CYP21 genes in the human genome, CYP21A1 (a pseudogene) and CYP21A2 (the functional gene). Deficiencies in steroid 21-hydroxylase activity lead to a type of congenital adrenal hyperplasia, which has three clinical forms: a severe form with concurrent defects in both cortisol and aldosterone biosynthesis; a form with adequate aldosterone biosynthesis; and a mild, non-classic form that can be asymptomatic or associated with signs of postpubertal androgen excess without cortisol deficiency. CYP21A2 is also the major autoantigen in autoimmune Addison disease. Cyp21 belongs to the large cytochrome P450 (P450, CYP) 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 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.
