Direct electron-transfer reactions of cytochrome c, ferredoxin and myoglobin at functional electrodes have been demonstrated and the functions of the suitable surfaces for the rapid electron-transfer have been discussed. Pyridyl promoter modified gold electrodes and positively charged polypeptide modified surfaces were effective for cytochrome c and ferredoxin, respectively. Highly hydrophilic surface of indium oxide electrodes gave well-defined voltammograms of both horse heart and sperm whale metmyoglobins. These functional electrodes are applicable to various bioelectrochemical measurements, to build up bioelectrocatalytic reactions with the aid of enzyme reactions, and to develop various electrofunctional devices on the basis of protein electrochemistry.
