The electrochemical behavior of Cu 2 Zn 2 SOD on mercury electrodes was studied by controlled potential electrolysis. By comparison of UV, Raman spectra and activity of Cu 2 Zn 2 SOD before electrochemical reduction and after re-oxidation, it is proved that the conformation and activity are not changed.
The electrochemical behavior of bovine erythrocyte superoxide dismutase (BESOD) on a hanging or dropping mercury electrode was studied by cyclic voltammetry (CV) and normal pulse polarography (NPP). Two defined peaks in CV or in NPP diagrams were attributed to the peaks of copper(II) and zinc(II), respectively. The electrode processes were irreversible and possessed an adsorptive characteristic. The...
