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 master transcriptional regulator of
CC the stationary phase and the general stress response.
CC {ECO:0000256|HAMAP-Rule:MF_00959}.
CC -!- SUBUNIT: Interacts with the RNA polymerase core enzyme.
CC {ECO:0000256|HAMAP-Rule:MF_00959}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00959}.
CC -!- SIMILARITY: Belongs to the sigma-70 factor family. RpoS subfamily.
CC {ECO:0000256|HAMAP-Rule:MF_00959}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00959}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
