Abstract
Chemical modifications that alter the net charge of residues in reduction-oxidation proteins influence the redox potential of the protein by changing the electrostatic potential at the redox center. If the locations of the modified charges are known, the shift in redox potential may be used to determine the effective dielectric constant for the interactions between the redox center and modified residues. From the shift in redox potential upon charge neutralization of specific lysines in the hemoprotein cytochrome c, an effective dielectric constant of approximately 50 is calculated for the electrostatic interaction between the modified lysines and heme iron in the native protein.
