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. {ECO:0000256|HAMAP-Rule:MF_00844}.
CC -!- SUBUNIT: Associates with stalled 50S ribosomal subunits.
CC {ECO:0000256|HAMAP-Rule:MF_00844}.
CC -!- SIMILARITY: Belongs to the NEMF family. {ECO:0000256|HAMAP-
CC Rule:MF_00844}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
CC {ECO:0000313|EMBL:KRO08542.1}.
