Title: The effects of ammonium sulfate and acid on horse and human serum butyrylcholinesterase (EC 3.1.1.8).

Authors: Miller, S K

Published In Comp Biochem Physiol B, (1987)

Abstract: 1. Results of laboratory experiments which compared horse and human serum butyrylcholinesterase (EC 3.1.1.8) with respect to their acid inactivation and ammonium sulfate protection show: 2. Horse serum butyrylcholinesterase is more resistant to inactivation at pH 3.0 than human serum butyrylcholinesterase. 3. The loss of activity at pH 3.0 for both horse and human butyrylcholinesterase does not follow first order kinetics. 4. Both human and horse serum butyrylcholinesterase are protected from pH 3.0 inactivation by ammonium sulfate concentrations up to 33% saturation (1.37 M).
