Abstract excerpt
Spontaneous mutations have been isolated in Escherichia coli that result in the constitutive expression of an emrKY promoter. These mutations were found to be single-nucleotide substitutions within the linker region of the sensor protein EvgS, which is part of a two-component regulatory system along with EvgA. In the linker mutants (evgSI and evgS4), emrKY expression became constitutive and MIC against sodium...
