An oxidase is any enzyme that catalyzes an oxidation/reduction reaction involving molecular oxygen (O₂) as the electron acceptor. In these reactions, oxygen is reduced to water (H₂O) or hydrogen peroxide (H₂O₂).

The oxidase are a subclass of the oxidoreductases.

[edit] Examples

An important example is cytochrome c oxidase, the key enzyme that allows the body to employ oxygen in the generation of energy and the final component of the electron transfer chain. Other examples of interest to psychologists areare:

• glucose oxidase
• monoamine oxidase
• cytochrome oxidase
• Xanthine oxidase
• L-gulonolactone oxidase
• laccase
• lysyl oxidase

[edit] Oxidase test

Main article: Oxidase test

In microbiology, the oxidase test is used as a phenotypic characteristic for the identification of bacterial strains; it determines whether a given bacterium produces cytochrome oxidases (and therefore utilizes oxygen with an electron transfer chain).
