On the chemical distinctions between cholinesterase and cholinoreceptor

It has been claimed that it is possible to distinguish chemically acetylcholinesterase from the cholinoreceptor by means of p-chloromercuribenzoate and dithiothreitol and consequently suggested, that the enzyme and receptor are separate proteins (1). The present study showed that these two substance...

description It has been claimed that it is possible to distinguish chemically acetylcholinesterase from the cholinoreceptor by means of p-chloromercuribenzoate and dithiothreitol and consequently suggested, that the enzyme and receptor are separate proteins (1). The present study showed that these two substances are inadequate for this purpose, since their activity is not specific for the cholinoreceptor, but extends over a wide range of pharmacological responses.
