title: Colicin V-treated Escherichia coli does not generate membrane potential.
abstract: Colicin V-treated Escherichia coli was inhibited in its capacity to carry out active transport of proline and was unable to generate a membrane potential. Colicin V also prevented membrane potential formation by isolated cytoplasmic membrane vesicles. We conclude that a primary effect of this colicin involves the cytoplasmic membrane as a target.
