CC         ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.13;
CC         Evidence={ECO:0000255|HAMAP-Rule:MF_00661};
CC   -!- SUBUNIT: Component of the RNA degradosome, which is a multiprotein
CC       complex involved in RNA processing and mRNA degradation.
CC       {ECO:0000255|HAMAP-Rule:MF_00661}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00661}.
CC   -!- SIMILARITY: Belongs to the DEAD box helicase family. RhlB subfamily.
