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