== Function ==
[https://www.uniprot.org/uniprot/ARFA_ECOLI ARFA_ECOLI] Rescues the ribosomes stalled at the 3' end of non-stop mRNAs. May induce hydrolysis of the ribosome-bound peptidyl-tRNA. This activity is crucial when the stalled ribosome cannot be rescued by the SsrA(tmRNA)-SmpB quality control system.<ref>PMID:21062370</ref> <ref>PMID:21435036</ref>
