Chemical Properties |
from bovine erythrocytes |
Uses |
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. |
Uses |
superoxide dismutase (polyoxyalkylene-modified) is used in cosmetic preparations to prevent drying and aging of the skin without causing irritation. |
Uses |
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. 1 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. It also catalyzes the dismutation of superoxide radicals to hydrogen peroxide and molecular oxygen. Plays a critical role in the defense of cells against the toxic effects of oxygen radicals. Competes with nitric oxide (NO) for superoxide anion (which reacts with NO to form peroxynitrite), thereby SOD promotes the activity of NO.3 SOD has also been shown to suppress apoptosis in cultured rat ovarian follicles, neural cell lines, and transgenic mice. |
Definition |
Any of a type of antioxidant metalloenzymes that occur in aerobic and facultatitive bacteria and in eukarotes. They catalyze a reaction in which two molecules of the highly toxic, highly reactive, superoxide anion is converted into one molecule each of hydrogen peroxide and molecular oxygen. |
Brand name |
Palosein Veterinary (Oxis). |
General 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.

Purification Methods |
The dismutase is purified by DEAE-Sepharose and copper chelate affinity chromatography. The preparation is homogeneous by SDS-PAGE, by analytical gel filtration chromatography and by isoelectric focusing [Weselake et al. Anal Biochem 155 193 1986, Fridovich J Biol Chem 244 6049 1969]. |
