Stepwise Binding of Two Azide Ions to the O An oxidase is an enzyme that catalyzes an oxidation-reduction reaction, especially one involving dioxygen (O 2) as the electron acceptor.In reactions involving donation of a hydrogen atom, oxygen is reduced to water (H 2 O) or hydrogen peroxide (H 2 O 2).Some oxidation reactions, such as those involving monoamine oxidase or xanthine oxidase, typically do not involve free molecular oxygen. Cytochrome c oxidase is the component of the respiratory chain that catalyzes the reduction of oxygen to water. It uses disks impregnated with a reagent such as N,N,N′,N′-tetramethyl-p-phenylenediamine (TMPD) or N,N-dimethyl-p-phenylenediamine (DMPD), which is also a redox indicator. oxidase with bound cytochrome Sergio Papa, Giuseppe Capitanio, Francesco Papa.
