 note = {application/pdf, 論文(Article), Electrode reactions of horseradish peroxidase (HRP) at pyrolytic graphite (PG) electrodes were examined by cyclic voltammetry. HRP gave a redox wave around -0.3 V (vs. Ag/AgCl) at pH 8,which was due to heme of the HRP adsorbed on the electrode : HRP(Fe^<3+>)_<ad> +e→HRP(Fe^<2+>)_<ad>. The addition of H_2O_2 to the HRP solution induced a catalytic reduction current at thc electrode around -0.4 V at pH 8 ; larger catalytic currents were obtained in acidic solutions. This catalytic reduction of H_2O_2 can be given as 2HRP(Fe^<2+>)_<ad>+H_2O2+2H^+→2HRP(Fe^<3+>)_<ad>+2H_2O, where the catalytic reduction took place favorably through the reduction of heme in HRP. but not through the free heme moiety dissociated from HRP., http://ci.nii.ac.jp/naid/110002907247},
