UniProtKB - Q5FJP6 (LEPA_LACAC)
Protein
Elongation factor 4
Gene
lepA
Organism
Lactobacillus acidophilus (strain ATCC 700396 / NCK56 / N2 / NCFM)
Status
Functioni
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.UniRule annotation
