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}.
