CC hydrolysis and RNA unwinding activity. {ECO:0000255|HAMAP-
CC Rule:MF_00967}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=ATP + H2O = ADP + H(+) + phosphate; Xref=Rhea:RHEA:13065,
CC ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.13;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00967};
CC -!- SUBUNIT: Interacts with the 50S ribosomal subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00967}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000255|HAMAP-Rule:MF_00967}.
CC -!- SIMILARITY: Belongs to the DEAD box helicase family. SrmB subfamily.
CC {ECO:0000255|HAMAP-Rule:MF_00967}.
