Acetyl cholin esterase ec 184.108.40.206 and butyryl cholin esterase ec 220.127.116.11 released from normal and dystrophic muscles by treatment with proteolytic enzymes
Comparative Biochemistry and Physiology C Comparative Pharmacology 73(1): 33-36
Skeletal muscle from C57BL dystrophic mice demonstrated decreased activities of acetylcholinesterase with increased activities of butyrylcholinesterase. These changes were less distinct when compared to those observed with 129 ReJ mice. Collagenase or trypsin treatment solubilized less acetylcholinesterase activity but more butyrylcholinesterase activity from muscle of C57BL dystrophic mice than from muscle of control mice. These treatments results in similar pattern of release of acetylcholinesterase activity from muscle of 129 ReJ mice, except that more acetylcholinesterase activity was released from dystrophic muscle (129 ReJ) than from control by pepsin treatment. The acetylcholinesterase activities released by proteolytic enzymes were characterized by sucrose density gradient centrifugation.
