Fig. 6. A minority of nog1∆C rei1∆C reh1∆C mutant pre-60S particles display aberrant rRNA conformations.

a Densities of classes N1–N3 of nog1∆C rei1∆C reh1∆C mutant particles solved at a resolution of 3.0–6.0 Å. Classes N1 and N2 are aligned with the atomic model of class R2, while class N3 is aligned with the atomic model of class R1. Note that ITS2 is missing from classes N2 and N3. b View of H68-69 (red) and H75-76 (magenta) from classes N1–N3.
