Glutathione-gated K+ channels of Escherichia coli carry out K+ efflux controlled by the redox state of the cell

The kinetics of K+ efflux across the membranes of i) wild-type Escherichia coli poisoned by the thiol reagent N-ethylmaleimide, ii) K+ retention mutants and iii) glutathione-deficient mutants, have revealed a common "K+ leaky phenotype"; it is characterized by a very high rate of K+ efflux...
