title: Acetylcholinesterase from Drosophila melanogaster. Identification of two subunits encoded by the same gene.
abstract: Purified acetylcholinesterase from Drosophila melanogaster is composed of a 55 kDa and a 16 kDa noncovalently associated subunit. Cleavage of disulfide bonds reveals that two 55 kDa polypeptides are linked together in native dimeric AChE. Western blots with two antibodies directed against the N- and C-termini of the predicted AChE primary sequence show that the 55 and 16 kDa polypeptides originate from proteolysis of the same precursor encoded by the Ace locus.
