Comments

| FUNCTION | DEAD-box RNA helicase involved in the assembly of the 50S ribosomal subunit. Has an RNA-dependent ATPase activity, which is specific for 23S rRNA, and a 3' to 5' RNA helicase activity that uses the energy of ATP hydrolysis to destabilize and unwind short rRNA duplexes. |
| CATALYTIC ACTIVITY | Reaction=ATP + H2O = ADP + phosphate + H(+); Xref=Rhea:RHEA:13065, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378, ChEBI:CHEBI:30616, ChEBI:CHEBI:43474, ChEBI:CHEBI:456216; EC=3.6.4.13; |
| SUBCELLULAR LOCATION | Cytoplasm. |
| DOMAIN | Contains an N-terminal domain that binds non-specifically to RNA and a C-terminal domain that binds specifically and tightly to hairpin 92 of 23S rRNA. |
| SIMILARITY | Belongs to the DEAD box helicase family. DbpA subfamily. |
