Myeloperoxidases, eosinophil peroxidases, and lactoperoxidases; This well conserved family of animal heme peroxidases contains members with somewhat diverse functions. Myeloperoxidases are lysosomal proteins found in azurophilic granules of neutrophils and the lysosomes of monocytes. They are involved in the formation of microbicidal agents upon activation of activated neutrophils (neutrophils undergoing respiratory bursts as a result of phagocytosis), by catalyzing the conversion of hydrogen peroxide to hypochlorous acid. As a heme protein, myeloperoxidase is responsible for the greenish tint of pus, which is rich in neutrophils. Eosinophil peroxidases are haloperoxidases as well, preferring bromide over chloride. Expressed by eosinophil granulocytes, they are involved in attacking multicellular parasites and play roles in various inflammatory diseases such as asthma. The haloperoxidase lactoperoxidase is secreted from mucosal glands and provides antibacterial activity by oxidizing a variety of substrates such as bromide or chloride in the presence of hydrogen peroxide.

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.

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.

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.
