SURVIVAL OF ESCHERICHIA-COLI-CELLS EXPOSED TO IODOACETATE AND CHLORODINITROBENZENE IS INDEPENDENT OF THE GLUTATHIONE-GATED K+ EFFLUX SYSTEMS KEFB AND KEFC
Ls. Ness et al., SURVIVAL OF ESCHERICHIA-COLI-CELLS EXPOSED TO IODOACETATE AND CHLORODINITROBENZENE IS INDEPENDENT OF THE GLUTATHIONE-GATED K+ EFFLUX SYSTEMS KEFB AND KEFC, Applied and environmental microbiology, 63(10), 1997, pp. 4083-4086
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.
