Peroxidases or peroxide reductases (EC number 1.11.1.x) are a large group of enzymes which play a role in various biological processes. They are named after the fact that they commonly break up peroxides, and should not be confused with other enzymes that produce peroxide, which are often oxidases.

Peroxidase is an enzyme in the group of oxidoreductases that is widely distributed in nature. It can catalyze the oxidation of various organic and inorganic substrates by reacting with hydrogen peroxide and similar molecules. Due to its wide catalytic activity, peroxidases can …

Peroxidases are enzymes that primarily function to oxidize hydrogen donors using peroxides. They have a high specificity for hydrogen peroxide and can accept a wide range of hydrogen donors, including polyphenols. These enzymes are glycoproteins with a hematin compound as a cofactor and have molecular weights ranging from 30 to 55 kDa.

2021年5月1日 · Peroxidase is an enzyme in the group of oxidoreductases that is widely distributed in nature. It can catalyze the oxidation of various organic and inorganic substrates by reacting with hydrogen peroxide and similar molecules.

Peroxidases represent a family of isoenzymes actively involved in oxidizing reactive oxygen species, innate immunity, hormone biosynthesis and pathogenesis of several diseases. Different types of peroxidases have organ, tissues, cellular and …

This peroxidase activity is essential for metabolism, protection against oxidative stress, and regulating redox signaling processes within human cells. Due to the multifaceted role of Prxs in numerous cellular contexts, studying Prxs’ function in health and disease is of high relevance.

Peroxidase activity is found in exocrine secretions including milk, tears, and saliva, as well as in vaginal fluid (Table 1), mostly derived from enzymes synthesized in the glands, but some activity derives from polymorphonuclear leukocytes (myeloperoxidase; MPO) or possibly eosinophils (eosinophil peroxidase; EPO).

2018年10月8日 · The peroxidase activity of cyt c /CL toward external peroxidase substrates is low; the major biological function of these complexes is oxidation of the polyunsaturated fatty acids (PUFA) of CL. Cyt c /CL peroxidase activity is implicated in the propagation of apoptosis.
