(A, B) Side-by-side comparison of the refined cryo-EM density maps with segmentation for the SA-like state of ATP-γ-S-bound human 26S proteasome mixed 10-fold molar excess non-cleavable M1-Ub6 without (A) or with (B) E6AP.
(C, D) Side-by-side comparison of the refined cryo-EM density maps with segmentation for the SD-like state of ATP-γ-S-bound human 26S proteasome mixed 10-fold molar excess non-cleavable M1-Ub6 without (A) or with (B) E6AP. The color scheme follows that of Figure 2B. The orientation displayed in (A)-(D) is identical for the CP.
