CC   -!- FUNCTION: Sigma factors are initiation factors that promote the
CC       attachment of RNA polymerase to specific initiation sites and are then
CC       released. {ECO:0000256|PIRNR:PIRNR000774}.
CC   -!- SIMILARITY: Belongs to the sigma-54 factor family.
CC       {ECO:0000256|ARBA:ARBA00008798, ECO:0000256|PIRNR:PIRNR000774}.
