CC   -!- FUNCTION: Inhibits RpoS proteolysis by regulating RssB activity,
CC       thereby increasing the stability of the sigma stress factor RpoS during
CC       oxidative stress. Its effect on RpoS stability is due to its
CC       interaction with RssB, which probably blocks the interaction of RssB
CC       with RpoS, and the consequent delivery of the RssB-RpoS complex to the
CC       ClpXP protein degradation pathway. {ECO:0000255|HAMAP-Rule:MF_02010}.
CC   -!- SUBUNIT: Interacts with RssB. {ECO:0000255|HAMAP-Rule:MF_02010}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_02010}.
CC   -!- SIMILARITY: Belongs to the GpW/Gp25 family. IraD subfamily.
CC       {ECO:0000255|HAMAP-Rule:MF_02010}.
