General description
研究领域:细胞信号传导。超氧化物歧化酶(SOD)存在于所有动物、植物和微生物的需氧细胞。它是一种低分子重量蛋白质,以三种不同形式存在,如锰SOD,铜–锌SOD和细胞外SOD。
Other Notes
在pH 7.8,25℃条件下,3.0mL反应体积中,一个单位可在黄嘌呤氧化酶的偶联系统中抑制细胞色素c的减少达到50%。黄嘌呤氧化酶浓度应每分钟产生 0.025±0.005 的初始 ΔA550 。
Application
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。它也被用作小鼠肝脏和肾脏样品中SOD测定的标准品。
Biochem/physiol Actions
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。
