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

CC   -!- SIMILARITY: Belongs to the IraP family. {ECO:0000255|HAMAP-
CC       Rule:MF_01198}.
