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.

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.

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 …

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 are a group of enzymes that play a crucial role in various biological processes, including the degradation of environmental pollutants and the catalysis of oxidation reactions. These ...

2011年1月13日 · Peroxidases are enzymes that use H2 O 2 as an electron acceptor (EC 1.11.1). In soils, fungi produce manganese peroxidase (EC 1.11.1.13), lignin peroxidase (EC 1.11.1.14) and other broad spectrum peroxidases (EC 1.11.1.7) that are known for their role in depolymerizing lignin.

By now, enzymes termed peroxidases represent a heterogeneous group of distinct enzyme families that operate by different catalytic principles and fulfill diverse biological functions, detoxifying H2O2 being just one of many aspects.

Peroxiredoxins (Prxs) are members of the antioxidant enzymes necessary for every living object in the three domains of life and play critical roles in controlling peroxide levels in cells. This comprehensive literature review aims to elucidate the peroxidase activity of Prxs, examining their roles and significance for organisms across various taxa.

Catalase and peroxidase are heme enzymes that catalyze reactions of hydrogen peroxide. 94,95 In catalase, the enzymatic reaction is the disproportionation of hydrogen peroxide (Reaction 5.82) and the function of the enzyme appears to be prevention of any buildup of that potentially dangerous oxidant (see the discussion of dioxygen toxicity in ...
