CC   -!- FUNCTION: DEAD-box RNA helicase involved in the assembly of the
CC       50S ribosomal subunit at low temperature. Exhibits RNA-stimulated
CC       ATP hydrolysis and RNA unwinding activity. {ECO:0000256|HAMAP-
CC       Rule:MF_00967}.
CC   -!- CATALYTIC ACTIVITY: ATP + H(2)O = ADP + phosphate.
CC       {ECO:0000256|HAMAP-Rule:MF_00967}.
CC   -!- SUBUNIT: Interacts with the 50S ribosomal subunit.
CC       {ECO:0000256|HAMAP-Rule:MF_00967}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|HAMAP-Rule:MF_00967}.
CC   -!- SIMILARITY: Belongs to the DEAD box helicase family. SrmB
CC       subfamily. {ECO:0000256|HAMAP-Rule:MF_00967}.
