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 is regulated in response to many different signals, at the levels of both synthesis and proteolysis. Previous work with...
