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|RuleBase:RU362124}.
CC   -!- SIMILARITY: Belongs to the sigma-70 factor family.
CC       {ECO:0000256|ARBA:ARBA00007788, ECO:0000256|RuleBase:RU362124}.
CC   -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC       whole genome shotgun (WGS) entry which is preliminary data.
