RL Submitted (FEB-2008) to the EMBL/GenBank/DDBJ databases.
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. Modulates RNA-binding and helicase activities of the
CC degradosome. {ECO:0000255|HAMAP-Rule:MF_00471}.
CC -!- SUBUNIT: Homotrimer. Binds to both RNA-binding sites in the C-terminal
CC region of Rne and to RhlB. {ECO:0000255|HAMAP-Rule:MF_00471}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00471}.
CC -!- SIMILARITY: Belongs to the RraA family. {ECO:0000255|HAMAP-
CC Rule:MF_00471}.
