The dimeric and monomeric forms of the acetylcholine receptor from Torpedo californica electroplax have been purified in the presence of lipids and reconstituted. A spectroscopic method was applied to study the rapid kinetics of cation transport mediated by each of the reconstituted AcChR oligomers. Both the AcChR dimer and monomer responded to carbamylcholine by mediating cation transport on the time scale of a few milliseconds. The responses to carbamylcholine were blocked by histrionicotoxin and by desensitization, demonstrating that both forms manifest pharmacological properties observed in vivo. Analysis of the fast ion transport produced by various agonist concentrations yielded estimated rates of transport through a single receptor channel. These were comparable for the monomer and dimer and in agreement with those obtained for a preparation containing a mixture of both oligomers.
