Superoxide dismutase (SOD) is an antioxidant enzyme involved in the defense system against reactive oxygen species (ROS). SOD catalyzes the dismutation reaction of superoxide radical anion (O2-) to hydrogen peroxide, which is then catalyzed to innocuous O2 and H2O by glutathione peroxidase and catalase. Several classes of SOD have been identified. Among them, Cu/Zn SOD, also known as cytosolic SOD or SOD1, is found in all eukaryotic species as a homodimeric 32 kDa enzyme containing one each of Copper and Zinc ion per subunit (2).
