Catalytic Properties of Cytochrome c Heme Peptides

Abstract

Several kinds of heme peptides of cytochrome c were prepared and examined on their two catalytic properties, cytochrome c oxidative effect and peroxidative effect. The unrigid coordination at the sixth ligand place of heme iron in heme peptide was proved to be responsible for the two effects. The characteristic roles of peptide moiety of heme peptide in the effects were also discussed.
