[The role of surface and transmembrane potentials in copper binding by Escherichia coli cells].
Cu2+-induced accumulation of Mg2+ ions by E. coli cells has been studied. The accumulation was demonstrated to take place only when the cell had endogenous energy resources. The data obtained and their correlation with the data on Cu2+ binding by bacterial cells and Cu2+-dependent streptomycin accumulation allowed to conclude that copper induced nonspecific potential-dependent influx of cations into cell.
