Özet

Copper-zinc superoxide dismutase (CuZnSOD; E.C:1.15.1.1) catalyzes the dismutation of the superoxide radical to hydrogen peroxide and oxygen. In this study, CuZnSOD was isolated from human erythrocytes using DEAE-celltilose chromatography and copper chelate affinity chromatography. The enzyme was purified 196.3 fold with 33.8% efficiency. The molecular weight of CuZnSOD was determined as 20 kDa by SDS-PAGE.
