Mutations that increase expression of the rpoS gene and decrease its dependence on hfq function in Salmonella typhimurium.

Journal of bacteriology - 1 Feb 1997

Brown L, Elliott T

Abstract excerpt

The RpoS transcription factor (also called sigmaS or sigma38) is required for the expression of a number of stationary-phase and osmotically inducible genes in enteric bacteria. RpoS is also a virulence factor for several pathogenic species, including Salmonella typhimurium. The activity of RpoS...
