Polarographic Reduction of the Heme Iron in Native Horse-Heart Cytochrome c

  • Chapter
Biological Aspects of Electrochemistry

Part of the book series: Experientia Supplementum ((EXS,volume 18))

Summary

Electrochemical relaxation techniques have been applied to the reduction of horse-heart cytochrome c in buffered solutions. It has been shown that protein in low concentration catalyzes the electrolytic reduction of oxygen, some characteristics of the protein-iron reduction are also described. The apparently different effects of cytochrome c and hemin on the reduction of oxygen, point to mechanistic differences in the reduction of the ferriporphyrins themselves.
