CC   -!- FUNCTION: Inhibits RpoS proteolysis by regulating RssB activity,
CC       thereby increasing the stability of the sigma stress factor RpoS
CC       especially during phosphate starvation, but also in stationary phase
CC       and during nitrogen starvation. Its effect on RpoS stability is due to
CC       its interaction with RssB, which probably blocks the interaction of
CC       RssB with RpoS, and the consequent delivery of the RssB-RpoS complex to
CC       the ClpXP protein degradation pathway. {ECO:0000255|HAMAP-
CC       Rule:MF_01198}.
CC   -!- SUBUNIT: Interacts with RssB. {ECO:0000255|HAMAP-Rule:MF_01198}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01198}.
CC   -!- SIMILARITY: Belongs to the IraP family. {ECO:0000255|HAMAP-
CC       Rule:MF_01198}.
