由四个相同的亚基组成，每个亚基的分子量为58000。将反应2H2O2催化为H2O+O2。过氧化氢酶与超氧化物歧化酶和谷胱甘肽过氧化物酶一起控制哺乳动物细胞中氧自由基的水平，并可能共同起到体细胞氧化防御的作用。 Composed of four identical subunits each with a molecular weight of 58,000. Catalyzes the reaction 2H2O2 to H2O+O2. Catalase, along with the superoxides dismutase and glutathione peroxidase, controls the levels of oxygen-derived free radicals in mammalian cells, and together may function as a somatic oxidant defense.
