title: Permeability to cobalt ions and action of colicin K in a mutant that overproduces cardiolipin.
abstract: A mutant of Escherichia coli that produces excess cardiolipin becomes less capable of transporting Co2+. Cardiolipin therefore does not act as an ionophore under these conditions. Colicin K brings about the typical increase in permeability to Co2+ in the mutant.
