Movement of the ribosome along an mRNA requires the universally-conserved translocase (EF-G in bacteria) that couples GTP hydrolysis to directed movement. Here the authors use time-resolved Cryo-EM to visualize the GTPase-powered step on native translocating ribosomes and capture key translocation intermediates.
