Function

[DBPA_BACSU] 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 (Probable).^[1] ^[2]

Publication Abstract from PubMed

The YxiN protein of Bacillus subtilis is a member of the DbpA subfamily of prokaryotic DEAD-box RNA helicases. Like DbpA, it binds with high affinity and specificity to segments of 23S ribosomal RNA as short as 32 nucleotides (nt) that include hairpin 92. Several experiments have shown that the 76-residue carboxy-terminal domain of YxiN is responsible for the high-affinity RNA binding. The domain has been crystallized and its structure has been solved to 1.7 Angstroms resolution. The structure reveals an RNA recognition motif (RRM) fold that is found in many eukaryotic RNA binding proteins; the RRM fold was not apparent from the amino acid sequence. The domain has two solvent exposed aromatic residues at sites that correspond to the aromatic residues of the ribonucleoprotein (RNP) motifs RNP1 and RNP2 that are essential for RNA binding in many RRMs. However, mutagenesis of these residues (Tyr404 and Tyr447) to alanine has little effect on RNA affinity, suggesting that the YxiN domain binds target RNAs in a manner that differs from the binding mode commonly found in many eukaryotic RRMs.

The domain of the Bacillus subtilis DEAD-box helicase YxiN that is responsible for specific binding of 23S rRNA has an RNA recognition motif fold.,Wang S, Hu Y, Overgaard MT, Karginov FV, Uhlenbeck OC, McKay DB RNA. 2006 Jun;12(6):959-67. Epub 2006 Apr 12. PMID:16611943^[3]
