Membranes from a mutant strain of Escherichia coli K12 carrying the uncD409 allele were washed in low-ionic-strength buffers in the presence or absence of the proteinase inhibitor p-aminobenzamidine. Unlike membranes from a normal strain, those from strain AN463 (uncD409) did not become proton-permeable, as judged by NADH-induced atebrinfluorescence quenching, when the membranes were washed in the absence of p-aminobenzamide. Furthermore, ATP-dependent atebrin-fluorscence quenching in such washed membranes could not be reconstituted by the addition of solubilized Mg2+-stimulated adenosine triphosphatase preparations. The examination by two-dimensional polyacrylamide-gel electrophoresis of the polypeptide composition of the washed membranes from strain AN463 (uncD409) indicated the presence of a polypeptide of similar molecular weight to the normal beta-subunit of the Mg2+-stimulated adenosine triphosphatase, but with an altered isoelectric point. Both the normal and abnormal beta-subunits were identified in membranes prepared from a partial diploid strain carrying both the unc+ and uncD409 alleles. It is concluded that the uncD gene codes for the beta-subunit of the Mg2+-stimulated adenosine triphosphatase.
