| Details | Protocol: rigid body. Manual fitting in O.The docking of X-ray structures into the cryo-EM maps was made using O and the visualization was performed in IRIS Explorer. EF-G domains were taken from the Thermus thermophilus H573A mutant crystal structure in complex with GDP (PDB code: 1FNM). The coordinates of the ribosomal proteins and rRNAs were taken from published atomic structures (PDB code 1FFK for the 50S subunit; 1FJF for the 30S subunit and the docking was performed using the coordinates as rigid bodies. |
