[Molecular forms of acetylcholinesterase in frog skeletal muscle: effects of denervation].
In the muscles of the frog, four main molecular forms of acetylcholinesterase are present, with sedimentation coefficients of 5.7, 10.4, 13 and 17.6 S. The heaviest forms, 13 S and 17.6 S are found in both nerve-free segments and endplates zones of sartorius muscle. They decrease in long-term denervation experiments. Consequently, these two forms are not specifically localized in endplates containing regions. However, they depend either on muscle activity or on neural influence or both.
