oxidase

 [ok´sĭ-dās]
any of a class of enzymes that catalyze the reduction of molecular oxygen independently of hydrogen peroxide.

ox·i·dase

(ok'si-dās),
Classically, one of a group of enzymes, now termed oxidoreductases (EC class 1), that bring about oxidation by the addition of oxygen to a metabolite or by the removal of hydrogen or of one or more electrons. Oxidase is now used for those cases in which O2 acts as an acceptor (of H or of electrons); those removing hydrogen are now termed dehydrogenases. For individual oxidases, see the specific names.

oxidase

/ox·i·dase/ (ok´sĭ-dās) any enzyme of the class of oxidoreductases in which molecular oxygen is the hydrogen acceptor.

oxidase

(ŏk′sĭ-dās′, -dāz′)
n.
Any of a group of enzymes that catalyze oxidation, especially an enzyme that reacts with molecular oxygen to catalyze the oxidation of a substrate.

ox′i·da′sic adj.

oxidase

[ok′sidās]
Etymology: Gk, oxys, sharp
an enzyme that induces biological oxidation by activating the oxygen in molecules containing the element, such as hydrogen peroxide.

ox·i·dase

(ok'si-dās)
One of a group of enzymes that bring about organic reactions in which O2 acts as an acceptor (of H or of electrons).

oxidase

an enzyme that catalyses a reaction in which oxygen is added to a substance (X) with hydrogen removed and water formed. Thus:

Most oxidases are proteins with metallic groups attached. For example, cytochrome oxidase contains iron and oxidizes cytochrome a in the ELECTRON TRANSPORT SYSTEM of aerobic respiration:
