Popis: The K72A/K73H/K79A mutant of yeast iso-1-cytochrome c immobilized on a conductive substrate reversibly interconverts between the native-like, His-Met heme-ligated form and a His-His-ligated conformer with remarkably different redox and enzymatic properties. This transition is activated by changing the pH in a narrow range around neutrality.
