Top The equilibrium binding constant of CD to maltoporin changes with NaCl concentration and shows pronounced dependence on the applied voltage. Bottom: Salt-induced changes in the free energy of CD binding to maltoporin derived from the binding constant at zero applied voltage are sensitive to salt species. δΔG is the difference between the binding free energy in 0.5 M NaCl solutions, where the measurements were routinely started, and the value of the ΔG at increased salt concentrations.
