| + | == Function == | ||
| + | [https://www.uniprot.org/uniprot/LEPA_ECOLI LEPA_ECOLI] Required for accurate and efficient protein synthesis under certain stress conditions. May act as a fidelity factor of the translation reaction, by catalyzing a one-codon backward translocation of tRNAs on improperly translocated ribosomes. Back-translocation proceeds from a post-translocation (POST) complex to a pre-translocation (PRE) complex, thus giving elongation factor G a second chance to translocate the tRNAs correctly. Binds to ribosomes in a GTP-dependent manner.<ref>PMID:17110332</ref> <ref>PMID:20045415</ref> | ||
