 Introduction: Long–acting, extremely stable form of catalase that is active from pH 2–12. Composed of four protein subunits, each containing a heme (Fe3+–protoporphyrin) group bound to its active site. Each subunit also contains one molecule of bound NADPH that helps to stabilize the enzyme. Catalyzes the reaction 2H2O2¨2H2O+O 2. Catalase, along with superoxide dismutase and glutathione peroxidase, controls the level of oxygen–derived free radicals in mammalian cells, and together may function as a somatic oxidant defense. Prevents apoptosis in cultured rat ovarian follicles.
