Peroxidase

Noun

1. Any of a group of enzymes (occurring especially in plant cells) that catalyze the oxidation of a compound by a peroxide.

Specialty Definitions: Peroxidase

Domain	Definitions
Health	A hemeprotein from leukocytes. Deficiency of this enzyme leads to a hereditary disorder coupled with disseminated moniliasis. It catalyzes the conversion of a donor and peroxide to an oxidized donor and water. EC 1.11.1.7. (references)

Specialty Definition: Peroxidase

(From Wikipedia, the free Encyclopedia)

A peroxidase is an enzyme, usually containing heme, that catalyzes a reaction of the form:

ROOR' + electron donor (2 e^-) + 2H⁺ → ROH + R'OH

Many of these compounds are optimally designed to process hydrogen peroxide.

The nature of the electron donor is very dependent on the specific nature of the enzyme itself. For a compound such as horseradish peroxidase, the number of organic compounds it can use as electron donors is substantial. Horseradish peroxidase has a broad and accessible active site and many compounds can reach the site of the reaction. For a compound such as cytochrome c peroxidase, the compounds that donate electrons are very specific, because there is a very closed active site.

Peroxidases are sometimes used as histological markers. Cytochrome c peroxidase is used as a soluble, easily purified model for cytochrome c oxidase.

Glutathione peroxidase is a peroxidase found in humans containing selenocysteine.
