An assessment is made of the proposal: electrostatic interactions between the ferric ion of oxidised cytochrome c and its haem propionate sidechains assits in determining the value of the redox potential and plays an important role in the redox state conformation change. Differences between the properties of homologous cytochromes are proposed to be due to differences associated with the charge on their haem propionates.
