MeSH

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.

Year introduced: 1994

A 66-kDa peroxidase found in EOSINOPHIL granules. Eosinophil peroxidase is a cationic protein with a pI of 10.8 and is comprised of a heavy chain subunit and a light chain subunit. It possesses cytotoxic activity towards BACTERIA and other organisms, which is attributed to its peroxidase activity.

Year introduced: 2005(1997)

The lectin wheatgerm agglutinin conjugated to the enzyme HORSERADISH PEROXIDASE. It is widely used for tracing neural pathways.

Year introduced: 1996

A hemeprotein that catalyzes the oxidation of the iodide radical to iodine with the subsequent iodination of many organic compounds, particularly proteins. EC 1.11.1.8.

Year introduced: 1986(1976)

An enzyme isolated from horseradish which is able to act as an antigen. It is frequently used as a histochemical tracer for light and electron microscopy. Its antigenicity has permitted its use as a combined antigen and marker in experimental immunology.

Year introduced: 1991(1976)

An enzyme catalyzing the oxidation of 2 moles of GLUTATHIONE in the presence of HYDROGEN PEROXIDE to yield oxidized glutathione and water.

Year introduced: 1984(1975)

A hemeprotein which catalyzes the oxidation of ferrocytochrome c to ferricytochrome c in the presence of hydrogen peroxide. EC 1.11.1.5.

Year introduced: 1994

An enzyme that catalyzes the chlorination of a range of organic molecules, forming stable carbon-chloride bonds. EC 1.11.1.10.

Year introduced: 1991(1976)

One of the most abundant isoenzymes of the glutathione peroxidase family. Located in the cytosol and mitochondria, it catalyzes the reduction of HYDROGEN PEROXIDE to water, functioning to limit the accumulation of hydrogen peroxide and modulating processes that utilize hydrogen peroxide; and also the reduction of other organic hydroperoxides to their corresponding alcohols.

Year introduced: 2023 (1999)

A selenoenzyme that converts GLUTATHIONE plus FATTY ACID HYDROPEROXIDES to GLUTATHIONE DISULFIDE plus hydroxy fatty acids and water.

Year introduced: 2020 (1990)

Immunologic techniques based on the use of: (1) enzyme-antibody conjugates; (2) enzyme-antigen conjugates; (3) antienzyme antibody followed by its homologous enzyme; or (4) enzyme-antienzyme complexes. These are used histologically for visualizing or labeling tissue specimens.

Year introduced: 1991

Peroxidases that utilize ASCORBIC ACID as an electron donor to reduce HYDROGEN PEROXIDE to WATER. The reaction results in the production of monodehydroascorbic acid and DEHYDROASCORBIC ACID.

Year introduced: 2012(1980)

Date introduced: April 25, 1993

A family of ubiquitously-expressed peroxidases that play a role in the reduction of a broad spectrum of PEROXIDES like HYDROGEN PEROXIDE; LIPID PEROXIDES and peroxinitrite. They are found in a wide range of organisms, such as BACTERIA; PLANTS; and MAMMALS. The enzyme requires the presence of a thiol-containing intermediate such as THIOREDOXIN as a reducing cofactor.

Year introduced: 2008(1988)

from many plants; amino acid sequence in first source

Date introduced: September 4, 1997

endosperm specific enzyme; amino acid sequence given in first source

Date introduced: October 15, 1991

conjugate of horseradish peroxidase & cholera toxin

Date introduced: July 1, 1987

Date introduced: February 13, 2005

from the roots of Norway spruce; GenBank AJ250121; do not confuse with SP12 protein which is a salivary protein

Date introduced: October 17, 2001
