case <OC:Bacteria>
Function | Part of the ribosome quality control system (RQC). Recruits Ala-charged tRNA and directs the elongation of stalled nascent chains on 50S ribosomal subunits, leading to non-templated C-terminal Ala extensions (Ala tail). The Ala tail promotes nascent chain degradation. May add between 1 and at least 8 Ala residues. Binds to stalled 50S ribosomal subunits. |
else case <OC:Archaea>
Function | Probably part of the ribosome quality control system (RQC). May mediate the addition of alanine residues (Ala tailing) to incompletely synthesized nascent chains from stalled ribosomes, leading to their degradation. |
end case
Subunit | Associates with stalled 50S ribosomal subunits. |
Similarity | Belongs to the NEMF family. |
