Translocation of peptidyl-tRNA and mRNA within the ribosome during protein synthesis is promoted by the elongation factor EF-G and by the hydrolysis of GTP. A new study reports that EF-G binds to ribosomes as an EF-G·GDP complex and that GTP is exchanged for GDP on the ribosome. Together with cryo-electron microscopy, this unexpected finding helps clarify the role of GTP in translocation.
