Potentiometric Titration and Conformational Change in Pepsinogen

Journal of Biological Chemistry, 1967
Abstract Potentiometric titrations of pepsinogen as functions of ionic strength and temperature were studied. It was found that the ionic strength has a minor effect on the titration behavior of the protein. The maximum values of the buffering capacity in the pH range of 6.0 to 9.0 were found at pH values corresponding to those at which a ...
