Biochem/physiol Actions
スーパーオキシドジムスターゼは、スーパーオキシドラジカルを過酸化水素と分子状酸素に分解する反応を触媒します。酸素ラジカルの毒性から細胞を保護する上で重要な役割を果たしています。スーパーオキシドアニオン(一酸化窒素(NO)と反応してペルオキシナイトライトを生成)と一酸化窒素(NO)が競合するため、SOD は NO の活性を促進します。SOD は、培養ラット卵巣卵濾胞、神経細胞株、および遺伝子導入マウスにおいてアポトーシスを抑制することも明らかにされています。

Application
Superoxide Dismutase from bovine liver has been used:
- for measuring mitochondrial hydrogen peroxide production in skeletal muscle
- as a positive control in Cu(II) binding stability assay
- as a positive control in superoxide dismutase assay
- in a study to assess the inactivation of endothelial-derived relaxing factor by oxidized lipoproteins.
- in a study to investigate the role of hydrogen peroxide in the cytotoxicity of the xanthine/xanthine oxidase system.
General description
Research area: Cell Signaling
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.
