产品概述

Lyophilized powder, ≥3,000 units / mg protein
Synonym: SOD, Superoxide: superoxide oxidoreductase
MW: 32.5 kDa 


Description

Superoxide dismutases are a group of low molecular weight metalloproteins present in all aerobic cells of plants, animals and micro-organisms. They provide protection against damaging reactions with the superoxide radical anion (O2-) by catalyzing its disproportionation into oxygen and hydrogen peroxide.

Application
Superoxide dismutase from bovine erythrocytes has been used in a study to assess a kinetic model of radiation-induced inactivation of superoxide dismutase in nitrous oxide-saturated solutions. Superoxide dismutase from bovine erythrocytes has also been used in a study to investigate the possible participation of superoxide anion in the intestinal tryptophan 2,3-dioxygenase reaction.

Physical form
Lyophilized powder, essentially salt-free


Storage temp
−20°C

产品简介
本品来源于牛红细胞。超氧化物歧化酶(SOD)催化去除氧自由基。这种酶保护氧代谢细胞免受超氧自由基的危害。超氧化物歧化酶被H2O2灭活。它由两个相同分子量的亚基组成,由二硫键连接。分子量为32500道尔顿,每个分子有两个Cu(II)和两个Zn(II)原子。酶的等电点是4.95。 超氧化物歧化酶是存在于植物、动物和微生物的所有需氧细胞中的一组低分子量金属蛋白。它们通过催化超氧自由基阴离子(O2-)歧化为氧和过氧化氢,来防止与超氧自由基阴离子(O2-)发生破坏性反应。
