It is found that two Eu^3+ ions would coordinate strongly with carboxylate oxygen of two propionic acid groups of the heme group in an MP-8 molecule, leading to the increase in the reversibility of the electrochemical reaction of MP-8. The excessive Eu^3+ ions weakly interact with the oxygen containing groups in the peptide chain of MP-8.展开更多
