An Ectocellular Form of Acetylcholinesterase on the Plasma Membrane of Nerve Terminals in Torpedo Electric Organ
In the present chapter, we will focus our attention on the presence of an amphiphilic, membrane-bound form of acetylcholinesterase which is localized at the external surface of nerve terminal plasma membranes in Torpedo electric organs. The experimental data have been described in detail (Li and Bon 1983) and similar results have been obtained by Morel and Dreyfus (1982). As described elsewhere in this volume by Vigny et al., acetylcholinesterase exists in multiple molecular forms. Therefore, we will first describe the polymorphism of acetylcholinesterase in Torpedo electric organs.
