For single-particle analysis, 20S proteasome (1 ug/uL) was incubated with 1 mM DNDDDLYG peptide dissolved in PBS for 15 minutes at room temperature. Copper EM grids with 200 mesh R1/4 carbon film (Quantifoil Micro Tools, Jena, Germany) were glow-discharged prior to sample vitrification using a Vitrobot Mark IV (Thermo Fisher Scientific) at 4 degrees C and 100% humidity. Three microliters of the sample were applied and blotted using FEI Vitrobot Perforated Filter Paper (Whatman) with a blot force of 3.5 for 4 seconds. |

Low-magnification images were taken at 11500x (object pixel size 2.13 nm) to generate lamella overviews. Tilt series were recorded at 1.89 A pixel size using the Tomography 5 (Thermo) in EER file format, with a dose-symmetric tilt scheme. The tilt series were collected with a 3 degree tilt increment with an angular range of ~120 degrees, and with cumulative dose of 80-120 electrons/A^2. Targeted defocus was in the range of -5 to -3 um. |
