Membrane potential stimulated binding of the maltose-binding protein to membrane vesicles of Escherichia coli.
We show in this study that radioactively labelled purified maltose-binding protein of Escherichia coli binds specifically to membrane vesicles, in the presence of maltose. When a potential is imposed across the membrane, the specific binding is increased, dependent on maltose, abolished in a mutant defective in the tar-gene product, one of the methyl-accepting chemotaxis proteins.
