Related to peroxidases: catalase, peroxidase reaction


[EC subclass 1.11] Enzymes in animal and plant tissues that catalyze the dehydrogenation (oxidation) of various substances in the presence of hydrogen peroxide, which acts as a hydrogen acceptor, being converted to water in the process.

peroxidases (p·räkˑ·s·dā·sz), enzymes that use peroxide to break down bacteria and other harmful material. Located in the granules of neutrophils.

peroxidases, the hydrogen peroxide-reducing enzymes, occurring in animal and plant tissues, that catalyze the dehydrogenation (oxidation) of various substances in the presence of hydrogen peroxide.
