DetailsREFINEMENT PROTOCOL--rigid body DETAILS--(1) TSV IRES was modeled with iFoldRNA and ModeRNA programs and then fitted into the cryo-EM map in Chimera. ...REFINEMENT PROTOCOL--rigid body DETAILS--(1) TSV IRES was modeled with iFoldRNA and ModeRNA programs and then fitted into the cryo-EM map in Chimera. (2) The 80S-IRES complex was refined against the map, using stereochemically restrained real-space refinement in RSRef.
