一般說明
Research area: Cell signaling. Superoxide Dismutase (SOD) is found in allaerobic cells of the animals, plants, and microorganisms. It is a low molecularweight protein that exists as three different forms such as manganese SOD,copper–zinc SOD, and extracellular SOD.
應用
来自牛红细胞的超氧化物歧化酶已用于评估佐剂诱导的关节炎的活性参数的研究中。 来自牛红细胞的超氧化物歧化酶也已用于一项研究中，以简化在10-羧基癸基琼脂糖凝胶上使用电荷控制的疏水色谱法纯化超氧化物歧化酶的过程。
生化／生理作用
牛红细胞来源的超氧化物歧化酶可催化超氧化物自由基歧化为过氧化氢和分子氧。作为一种抗氧化剂，它在保护细胞免受氧自由基毒性作用方面起着至关重要的作用。与一氧化氮(NO)竞争超氧化物阴离子（可与NO反应生成过亚硝酸盐），因此SOD能促进NO的活性。在培养的大鼠卵泡、神经细胞系和转基因小鼠中，SOD也表现出抑制细胞凋亡的作用。
