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

S Miller1, L S Ness, C M Wood, B C Fox, I R Booth.   

Abstract

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.
