Three types of electroactive peptides were synthesized with 16 amino acids, which had a flavin pendant at three different sites of the α-helical peptide. Each flavin-pendant α-helical peptide was self-assembled on a gold electrode through Cys-S(H) at the C-terminus, and electrochemically characterized. All of these flavin-pendant peptides performed excellent characteristics in electron transfer at the electrode/solution interface. In the results, it was strongly suggested that the rate constant of the flavin redox reaction was determined by the molecular environment surrounding the flavin.
