Technical Data
Superoxide Dismutase, Mn (Manganese Superoxide Dismutase, Manganese SOD, Mn SOD, MnSOD, IPO-B, Superoxide Dismutase [Mn] Mitochondrial Precursor, Superoxide Dismutase 2 Mitochondrial, SOD 2, SOD2, SOD-2)
Superoxide dismutase (SOD) is an endogenously produced intracellular enzyme present in almost every cell in the body. It works by catalyzing the dismutation of the superoxide radical O2- to O2 and H2O2, which are then metabolized to H2O and O2 by catalase and glutathione peroxidase. In general, SODs play a major role in antioxidant defense mechanisms. There are two main types of SOD in mammalian cells. One form (SOD1) contains Cu and Zn ions as a homodimer and exists in the cytoplasm. The two subunits of 16kD each are linked by two cysteines forming an intra-subunit disulfide bridge. The second form (SOD2) is a manganese containing enzyme and resides in the mitochondrial matrix. It is a homotetramer of 80kD. The third form (SOD3 or EC-SOD) is like SOD1 in that it contains Cu and Zn ions, however it is distinct in that it is a homotetramer, with a mass of 30kD and it exists only in the extracellular space. SOD3 can also be distinguished by its heparin-binding capacity.
