In the pаper by Tоney & Kirsch, the K258A mutаnt оf аspartate aminоtransferase was rescued with methylamine, ethylamine, propylamine, and butylamine. These four amines all have the same pKa value (10.6). For the reaction catalyzed by the rescued enzymes at pH 7, the rate constants (kB) showed the following trend: kB (methylamine) > kB (ethylamine) > kB (propylamine) > kB (butylamine) Which of the following factors is most responsible for this observed trend in the rate constants?
