Identification of an ancillary protein, YabF, required for activity of the KefC glutathione-gated potassium efflux system in Escherichia coli.

Journal of bacteriology - 1 Nov 2000

Miller S, Ness L S, Wood C M, Fox B C, Booth I R

Abstract excerpt

A new subunit, YabF, for the KefC K(+) efflux system in Escherichia coli has been identified. The subunit is required for maximum activity of KefC. Deletion of yabF reduces KefC activity 10-fold, and supply of YabF in trans restores activity. IS2 and IS10R insertions in yabF can be isolated as suppressors of KefC activity consequent upon the V427A and D264A KefC mutations.
