Abstract :

Previous studies have shown that channel formation in the cytoplasmic membrane of Escherichia coli by colicin A and phage T5 leads to an efflux of cytoplasmic potassium and to a membrane depolarization. Here we show that upon opening of these channels, the intracellular ATP concentration is decreased to 10% of its original value in
