  • Title: Survival of Escherichia coli cells exposed to iodoacetate and chlorodinitrobenzene is independent of the glutathione-gated K+ efflux systems KefB and KefC.
    Author: Ness LS, Ferguson GP, Nikolaev Y, Booth IR.
    Journal: Appl Environ Microbiol; 1997 Oct; 63(10):4083-6. PubMed ID: 9327573.
    Abstract:
    The KefB and KefC systems of Escherichia coli cells are activated by iodoacetate (IOA) and chlorodinitrobenzene (CDNB), leading to a rapid drop in the intracellular pH. However, survival of exposure to IOA or CDNB was found to be essentially independent of KefB and KefC activation. No correlation was found between the toxicity of the compound and its ability to elicit protective acidification via activation of KefB and KefC.
