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.

cytochrome P450 family 1, subfamily A; Cytochrome P450 family 1, subfamily A (CYP1A) consists of two human members, CYP1A1 and CYP1A2, which overlap in their activities. CYP1A2 is the highly expressed cytochrome enzyme in the human liver, while CYP1A1 is mostly found in extrahepatic tissues. Known common substrates include aromatic compounds such as polycyclic aromatic hydrocarbons, arachidonic acid and eicosapentoic acid, as well as melatonin and 6-hydroxylate melatonin. In addition, CYP1A1 activates procarcinogens into carcinogens via epoxides, and metabolizes heterocyclic aromatic amines of industrial origin. CYP1A2 metabolizes numerous natural products that result in toxic products, such as the transformation of methyleugenol to 1'-hydroxymethyleugenol, estragole to reactive metabolites, and oxidation of nephrotoxins. It also plays an important role in the metabolism of several clinical drugs including analgesics, antipyretics, antipsychotics, antidepressants, anti-inflammatory, and cardiovascular drugs. The CYP1A subfamily 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 family 17, subfamily A, polypeptide 1; Cytochrome P450 17A1 (CYP17A1 or Cyp17a1), also called cytochrome P450c17, steroid 17-alpha-hydroxylase (EC 1.14.14.19)/17,20 lyase (EC 1.14.14.32), or 17-alpha-hydroxyprogesterone aldolase, catalyzes the conversion of pregnenolone and progesterone to their 17-alpha-hydroxylated products and subsequently to dehydroepiandrosterone (DHEA) and androstenedione. It is a dual enzyme that catalyzes both the 17-alpha-hydroxylation and the 17,20-lyase reactions. Severe mutations on the enzyme cause combined 17-hydroxylase/17,20-lyase deficiency (17OHD); patients with 17OHD synthesize 11-deoxycorticosterone (DOC) which causes hypertension and hypokalemia. Loss of 17,20-lyase activity precludes sex steroid synthesis and leads to sexual infantilism. Included in this group is a second 17A P450 from teleost fish, CYP17A2, that is more efficient in pregnenolone 17-alpha-hydroxylation than CYP17A1, but does not catalyze the lyase reaction. CYP17A1 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.

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.

Plant cytochrome P450s, clan CYP71; The number of cytochrome P450s (P450s, CYPs) in plants is considerably larger than in other taxa. In individual plant genomes, CYPs form the third largest family of plant genes; the two largest gene families code for F-box proteins and receptor-like kinases. CYPs have been classified into families and subfamilies based on homology and phylogenetic criteria; family membership is defined as 40% amino acid sequence identity or higher. 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). The CYP71 clan has expanded dramatically and represents 50% of all plant CYPs; it includes several families including CYP71, CYP73, CYP76, CYP81, CYP82, CYP89, and CYP93, among others. It 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.

unknown subfamily of cytochrome P450s; This subfamily is composed of uncharacterized cytochrome P450s. 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 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.
