Protein
RNA polymerase sigma factor SigS
Organism
Staphylococcus aureus (strain bovine RF122 / ET3-1)
Function
Sigma factors are initiation factors that promote the attachment of RNA polymerase to specific initiation sites and are then released. Sigma-S contributes to the protection against external stress, thus playing a role in cellular fitness and survival (By similarity).
Similarity
Belongs to the sigma-70 factor family.
