Linkage plot. The slope indicates a net release of 7.6 ± 0.6 ions for the binding of thrombin to the γ′ peptide. Assuming that counterions are released from protein groups forming ion pairs, the data indicate that 3–4 ion pairs formed between thrombin and the γ′ peptide, with net release to solvent of associated counterions.
