The Electrochemical Behaviors of Superoxide Dismutase at Promoter Modified Gold Electrode

Wu Xiaqin * Meng Xiaoyun Wang Zhesu Zhang Zongrang Dept of Chem,Shanghai Normal Univ, Shanghai 200234  
The electron_transfer process of superoxide dismutase was investigated by cyclic voltammetry at the 4,4'_dithiodipyridine,L_cysteine,histidine and arginine modified gold wire electrodes repectively.The quasi_reversible behavior was observed at L_cysteine modified gold electrode.An irreversible electrochemical behavior has been observed at hisdinine modified gold wire electrode.
