GP Ferguson, Y Nikolaev, D McLaggan… - Journal of …, 1997 - Am Soc Microbiol
The role of the KefB and KefC potassium efflux systems in protecting Escherichia coli cells
against the toxic effects of the electrophile N-ethylmaleimide has been investigated …

Mutations in the glutathione-gated KefC K+ efflux system of Escherichia coli that cause constitutive activation

S Miller, RM Douglas, P Carter, IR Booth - Journal of Biological Chemistry, 1997 - ASBMB
The kefC gene of Escherichia coli encodes a potassium efflux system that is gated by
glutathione (GSH) and by GSH adducts. Independently isolatedkefC mutations that result in …

Survival of Escherichia coli cells exposed to iodoacetate and chlorodinitrobenzene is independent of the glutathione-gated K+ efflux systems KefB and KefC

LS Ness, GP Ferguson, Y Nikolaev… - Applied and …, 1997 - Am Soc Microbiol
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 …
