Oxidoreductase: Oxidoreductase, any member of a class of enzymes, commonly known as dehydrogenases or oxidases, that catalyze the removal of hydrogen. Items 1 – 15 of 84 Oxidoreductases (EC 1.) comprise the large class of enzymes that catalyze biological oxidation/reduction reactions. They play an important role. The Enzyme List. Class 1 — Oxidoreductases. Nomenclature Committee of the. International Union of Biochemistry and Molecular Biology. (NC-IUBMB).

You can make it easier for us to review and, hopefully, publish your contribution by keeping a few points in mind. Simple question deserves a straightforward answer:.

Please note that our editors may make some formatting changes or correct spelling or grammatical errors, and may also contact you if any clarifications are needed. Dihydroorotate dehydrogenase Coproporphyrinogen III oxidase Protoporphyrinogen oxidase Bilirubin oxidase Acyl-CoA oxidase Dihydrouracil oxidase Tetrahydroberberine oxidase Secologanin synthase Tryptophan alpha,beta-oxidase Pyrroloquinoline-quinone synthase L-galactonolactone oxidase.

Ask New Question Sign In. Oxidoreductases are a class of enzymes that catalyze the transfer of electrons from one molecule to another.

Hydroxylases add hydroxyl groups to its substrates. He owes his success to 1 strategy. Other enzymes of this group catalyze such reactions as the oxidation of aldehydes and ketones to carboxylic acids and the dehydrogenation of amino acids.


They can be found in glycolysis, TCA cycle, oxidative phosphorylation, and in amino acid metabolism.

What is the function of digestive enzymes? We welcome suggested improvements to any of our articles. Active Site of NAD.

What is the function of enzymes in the stomach? Peroxidases are localized in peroxisomes, and catalyzes the reduction of hydrogen peroxide. What is the function of alcohol dehydrogenase enzyme? Oxidoreductases are a class of enzymes that catalyze oxidoreduction reactions They can be found in both aerobic and anaerobic pathways, including glycolysis, TCA cycle, oxidative phosphorylation, and amino acid metabolism.

This page was last edited on 4 Decemberat Retrieved from ” https: The reactions seem to proceed through Fe IV compounds with another unpaired electron electron on the porphyrin, which becomes oxirredutaases radical cation.

What are Oxidoreductases?

Education, discipline that is concerned with methods of teaching and learning in schools or school-like…. Internet URLs are the best. Oxygenases oxidize a substrate by incorporating oxygen to it.

Coenzyme Q – cytochrome c reductase. This tool looks for lower prices at other stores while you shop on Amazon and tells you where to buy.


How is the structure and function of enzymes related? Oxidoreductases catalyze reactions similar to this example: Reductases could also be oxidases since most redox reactions are reversible. Similar intermediates are also known in simpler porphyrin molecules.

The molecule that gives the electrons are called the electron donor or reductant, and the one receiving the electrons are called the electron acceptor or oxidant. Oxidoreductases catalyze the transfer of electrons from one molecule the oxidant to another molecule the reductant. Creative Enzymes proudly offers spectrophotometric enzyme assays in quantification of activity levels for all types of oxidoreductase enzymes: What are the biological function of enzymes?


This type of reaction is also known as a oxidoreduction reaction. Policies and guidelines Contact us. Keep Exploring Britannica Photosynthesis. This allows the carbon skeletons of the amino acids to be converted into oxaloacetate and subsequently into pyruvate.

At the bottom of the article, feel free to list any sources that support your changes, so that we can fully understand their context. Sarcosine dehydrogenase Cytokinin dehydrogenase. The feedback you provide will help us show you more relevant content in the future. For example, an alcohol dehydrogenase catalyzes the oxidation reaction of ethanol to form an aldehyde.

The lactate is then oxidized to pyruvate in muscle and liver cells, and the pyruvate is further oxidized in the TCA cycle. The structure of a human cytochrome P reductase EC 1. Coenzyme F hydrogenase 5,Methenyltetrahydromethanopterin hydrogenase Methanosarcina-phenazine hydrogenase Sulfhydrogenase. A group of cytochromes serve as oxidation-reduction agents, converting the energy of the oxidation process into the synthesis of adenosine triphosphate Ensimaswhich makes the energy more available to other reactions.
