CC   -!- FUNCTION: Sigma factors are initiation factors that promote the
CC       attachment of RNA polymerase to specific initiation sites and are then
CC       released. This sigma factor is responsible for the expression of
CC       sporulation specific genes.
CC   -!- SIMILARITY: Belongs to the sigma-70 factor family. {ECO:0000305}.
