Similar to other cytochromec peroxidases, they reduce hydrogen peroxide to water using c type haem as an oxidizable Enzyme substrate substrate . However, since they possess two, instead of one, haem prosthetic groups , this family of bacteria bacterial CCPs reduce hydrogen peroxide without the need to generate semi stable free radical s.

An oxidase is any enzyme that catalyst catalyzes an redox oxidation reduction reaction involving molecular oxygen O sub 2 sub as the electron acceptor. In these reactions, oxygen is reduced to water H sub 2 sub O or hydrogen peroxide H sub 2 sub O sub 2 sub . The oxidases are a subclass of the oxidoreductase s. Examples An important example is cytochromecoxidase , 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 are glucose oxidase monoamine oxidasecytochrome P450 oxidase NADPH oxidase Xanthine oxidase L gulonolactone oxidase laccase lysyl oxidaseOxidase test main Oxidase test In microbiology , the oxidase test is used as a Phenotype phenotypic characteristic for the identification of bacteria l strains it determines whether a given bacterium produces cytochrome oxidases and therefore utilizes oxygen with an electron transfer chain .
