Description | Superoxide dismutase is widely present in the human body, including the skin and its appendages. |
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.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.Superoxide dismutase(SOD) has also been shown to suppress apoptosis in cultured rat ovarian follicles, neural cell lines, and transgenic mice.superoxide dismutase (polyoxyalkylene-modified) is used in cosmetic preparations to prevent drying and aging of the skin without causing irritation. |
Uses | Superoxide dismutase is used as an excellent therapeutic agent to combat reactive oxygen species-mediated diseases such as cancer, inflammatory diseases, cystic fibrosis, ischemia, aging, rheumatoid arthritis, neurodegenerative diseases, and diabetes. However, the enzyme has some limitations in clinical applications. Therefore, SOD conjugates and mimetics have been developed to improve its therapeutic efficiency. |
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. |
Biochem/physiol Actions | 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. SOD has also been shown to suppress apoptosis in cultured rat ovarian follicles, neural cell lines, and transgenic mice. |
Clinical Use | Superoxide dismutase is widely studied and used for anti-inflammatory, anti-tumor, radiation protection and anti-aging applications. |
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. |
