Superoxide Dismutase

Title: Superoxide Dismutase
CAS Registry Number: 9054-89-1
Additional Names: SOD
Literature References: Family of naturally occurring metalloenzymes that act as free oxygen radical scavengers and protect against the deleterious effects of biologically generated superoxide oxygen radicals (O2.-) by dismutation to hydrogen peroxide (H2O2) + molecular oxygen (O2). Three metallotypes have been described; distinguished by the metal found at the active site: cupro-zinc containing (Cu/Zn SOD), manganese containing (Mn SOD), and iron containing (Fe SOD). Widely distributed, present in almost all aerobic organisms and some anaerobes. Isoln and purification of Cu/Zn SOD from bovine erythrocytes and identity with erythrocuprein (hemocuprein): J. M.
