Abstract

Salt addition to enzymes in buffer always induce the problem of the respective influences of electrostatic interactions and anion specificity on buffer pH and enzyme kinetics. In the present paper the influence of some sodium salts (Na2SO4, NaCl, NaBr and NaNO3) on the pH of a citrate buffer (c = 0.025 M), and on the catalytic constants of horseradish peroxidase (HRP) is studied. First, the pH ...
