Polypeptides Endowed with Artificial Redox Functions
Polypeptides carrying 2-anthraquinonyl groups or ferrocenyl groups were synthesized. Poly(l-2-anthraquinonylalanine) was found to form left-handed a-helical main chain and the anthraquinonyl side groups were arranged helically along the main chain. The anthraquinonyl polypeptide showed a unique redox property that was attributed to fast electron migrations along the anthraquinonyl side groups. Poly(l-ferrocenylalanine) was also synthesized. The latter polypeptide was found to take randomly-coiled conformations.
