Abstract
IONIZED salts affect choline acetyltransferase, EC 2.3.1.6 (ChA), in two important ways. They change the equilibrium between soluble and membrane-bound ChA, in preparations of ruptured nerve endings1,2. Further, the rate of synthesis of acetylcholine by soluble ChA and the Michaelis constants for this reaction depend on the concentration of salts3. The relevance of these effects to the role of ChA in nerve function and the mechanisms responsible are unknown. Our observations clarify the effect of salts on the soluble enzyme.
