Refinement Target The X-ray crystallographic structure of the EF-G individual domains were fitted into the cryo-EM map of the 70S*EF-G-UG*GDP*Fusidic acid complex using O. The G' domain within domain I was separately fitted, using a combination of manual rigid-body docking and flexible docking approaches, and taking into consideration both the cryo-EM envelope and the positional constraints imposed by the UG density. X-ray crystallographic structures of the N-terminal domain of protein L11 and C-terminal domain of protein L7/L12 were fitted as rigid bodies.
