Abstract
The KefB and KefC systems of Escherichia coli cells are activated by i odoacetate (IOA) and chlorodinitrobenzene (CDNB), leading to a rapid d rop in the intracellular pH. However, survival of exposure to IOA or C DNB was found to be essentially independent of KefB and KefC activatio n. No correlation was found between the toxicity of the compound and i ts ability to elicit protective acidification via activation of KefB a nd KefC.
