Fitting Procedure ?
Details METHOD--manual REFINEMENT PROTOCOL--Fitted as rigid body. Current model was aligned to the helix A of the fitted eEF2 coordinates (PDB entry 3DNY) which is located next to the switch I sequence. The coordinates for this entry are based on manual fitting of the coordinates into cryo-EM density map. Therefore, authors did not deposit structure factors.
