Any change in the pH of a protein’s environment will cause observable changes in the solubility of the protein. These changes reflect changes in the three-dimensional structure of the protein. The effect of pH on protein solubility explains why most enzymes function well at an optimum pH, and why their activity decreases substantially at pH values other than the optimum.
