Myeloperoxidase, Human Polymorphonuclear Leukocytes
Native, human myeloperoxidase from polymorphonuclear leukocytes. A lysosomal enzyme that catalyzes oxidations by hydrogen peroxide, including MPO-chloride-mediated killing of microbes and tumor cells, inactivation of chemotactic factors, and cross-linking of proteins. MPO catalyzes the formation of hypochlorous acid that kills bacteria either by binding the halide ion to intracellular constituents or by oxidation of bacterial lipids and proteins.
