Enzyme Information

Elongation factor 4.
based on mapping to UniProt P60785
GTP + H(2)O = GDP + phosphate.
-!- The enzyme is 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.
