Protein
RNA polymerase sigma factor RpoS
Organism
Salmonella typhimurium (strain ATCC 68169 / UK-1)
Function
Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. This sigma factor is the master transcriptional regulator of the stationary phase and the general stress response, including response to organic acid stress.
Similarity
Belongs to the sigma-70 factor family. RpoS subfamily.
