CC   -!- FUNCTION: Binds RpoD and negatively regulates RpoD-mediated
CC       transcription activation by preventing the interaction between the
CC       primary sigma factor RpoD with the catalytic core of the RNA polymerase
CC       and with promoter DNA. May be involved in replacement of the RNA
CC       polymerase sigma subunit from RpoD to RpoS during the transition from
CC       exponential growth to the stationary phase. {ECO:0000255|HAMAP-
CC       Rule:MF_01181}.
CC   -!- SUBUNIT: Interacts with RpoD. {ECO:0000255|HAMAP-Rule:MF_01181}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01181}.
CC   -!- SIMILARITY: Belongs to the Rsd/AlgQ family. {ECO:0000255|HAMAP-
CC       Rule:MF_01181}.
