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.

Linoleate (8R)-dioxygenase and related enzymes; These fungal enzymes, related to animal heme peroxidases, catalyze the oxygenation of linoleate and similar targets. Linoleate (8R)-dioxygenase, also called linoleate:oxygen 7S,8S-oxidoreductase, generates (9Z,12Z)-(7S,8S)-dihydroxyoctadeca-9,12-dienoate as a product. Other members are 5,8-linoleate dioxygenase (LDS, ppoA) and linoleate 10R-dioxygenase (ppoC), involved in the biosynthesis of oxylipins.

C-terminal cytochrome P450 domain of linoleate diol synthase and similar cytochrome P450s; This family contains Gaeumannomyces graminis linoleate diol synthase (LDS) and similar proteins including Ssp1 from the phytopathogenic basidiomycete Ustilago maydis. LDS, also called linoleate (8R)-dioxygenase, catalyzes the dioxygenation of linoleic acid to (8R)-hydroperoxylinoleate and the isomerization of the resulting hydroperoxide to (7S,8S)-dihydroxylinoleate. Ssp1 is expressed in mature teliospores, which are produced by U. maydis only after infection of its host plant, maize. Ssp1 is localized on lipid bodies in germinating teliospores, suggesting a role in the mobilization of storage lipids. LDS and Ssp1 contain an N-terminal dioxygenase domain related to animal heme peroxidases, and a C-terminal cytochrome P450 domain. The LDS-like 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.

Animal prostaglandin endoperoxide synthase and related bacterial proteins; Animal prostaglandin endoperoxide synthases, including prostaglandin H2 synthase and a set of similar bacterial proteins which may function as cyclooxygenases. Prostaglandin H2 synthase catalyzes the synthesis of prostaglandin H2 from arachidonic acid. In two reaction steps, arachidonic acid is converted to Prostaglandin G2, a peroxide (cyclooxygenase activity) and subsequently converted to the end product via the enzyme's peroxidase activity. Prostaglandin H2 synthase is the target of aspirin and other non-steroid anti-inflammatory drugs such as ibuprofen, which block the substrate's access to the active site and may acetylate a conserved serine residue. In humans and other mammals, prostaglandin H2 synthase (PGHS), also called cyclooxygenase (COX) is present as at least two isozymes, PGHS-1 (or COX-1) and PGHS-2 (or COX-2), respectively. PGHS-1 is expressed constitutively in most mammalian cells, while the expression of PGHS-2 is induced via inflammation response in endothelial cells, activated macrophages, and others. COX-3 is a splice variant of COX-1.

Animal heme oxidases similar to plant pathogen-inducible oxygenases; This is a diverse family of oxygenases related to the animal heme peroxidases, with members from plants, animals, and bacteria. The plant pathogen-inducible oxygenases (PIOX) oxygenate fatty acids into 2R-hydroperoxides. They may be involved in the hypersensitive reaction, rapid and localized cell death induced by infection with pathogens, and the rapidly induced expression of PIOX may be caused by the oxidative burst that occurs in the process of cell death.

peroxinectin_like animal heme peroxidases; Peroxinectin is an arthropod protein that plays a role in invertebrate immunity mechanisms. Specifically, peroxinectins are secreted as cell-adhesive and opsonic peroxidases. The immunity mechanism appears to involve an interaction between peroxinectin and a transmembrane receptor of the integrin family. Human myeloperoxidase, which is included in this wider family, has also been reported to interact with integrins.

Thyroid peroxidase (TPO); TPO is a member of the animal heme peroxidase family, which is expressed in the thyroid and involved in the processing of iodine and iodine compounds. Specifically, TPO oxidizes iodide via hydrogen peroxide to form active iodine, which is then, for example, incorporated into the tyrosine residues of thyroglobulin to yield mono- and di-iodotyrosines.
