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 the primary sigma factor during
CC exponential growth. {ECO:0000256|HAMAP-Rule:MF_00963}.
CC -!- SUBUNIT: Interacts transiently with the RNA polymerase catalytic core.
CC {ECO:0000256|HAMAP-Rule:MF_00963}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00963}.
CC -!- SIMILARITY: Belongs to the sigma-70 factor family. RpoD/SigA subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_00963}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00963}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:RCG32780.1}.
