CC   -!- FUNCTION: Sigma factors are initiation factors that promote the
CC       attachment of RNA polymerase to specific initiation sites and are then
CC       released. Sigma-S contributes to the protection against external
CC       stress, thus playing a role in cellular fitness and survival (By
CC       similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the sigma-70 factor family. {ECO:0000305}.
