| 摘 要： | The interaction sites between microperoxidase-8(MP-8) and Eu^3 was determined using electrochemical techniques. 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. |

| Abstract: | The interaction sites between microperoxidase-8(MP-8) and Eu~(3 ) was determined using electrochemical techniques. 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. |
| Keywords: | microperoxydase-8 Eu~(3 ) cyclic voltammetry europium ion |
