Fis regulates transcriptional induction of RpoS in Salmonella enterica.

Abstract excerpt

The sigma factor RpoS is known to regulate at least 60 genes in response to environmental sources of stress or during growth to stationary phase (SP). Accumulation of RpoS relies on integration of multiple genetic controls, including regulation at the levels of transcription, translation, protein stability, and protein activity. Growth to SP in rich medium results in a 30-fold induction of RpoS, although the...
