CC   -!- FUNCTION: Globally modulates RNA abundance by binding to RNase E (Rne)
CC       and regulating its endonucleolytic activity. Can modulate Rne action in
CC       a substrate-dependent manner by altering the composition of the
CC       degradosome. {ECO:0000255|HAMAP-Rule:MF_01888}.
CC   -!- SUBUNIT: Interacts with the C-terminal region of Rne.
CC       {ECO:0000255|HAMAP-Rule:MF_01888}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_01888}.
CC   -!- SIMILARITY: Belongs to the RraB family. {ECO:0000255|HAMAP-
CC       Rule:MF_01888}.
