Protein
Elongation factor 4
Gene

Organism
Mycoplasma pneumoniae (strain ATCC 29342 / M129)
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 By similarity.UniRule annotation

Catalytic activityi

GTP + H2O = GDP + phosphate.UniRule annotation
