Translations

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.

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:
