Extended Data Fig. 4: Comparison of Ump1 before and after CP fusion.
From: Mechanism of autocatalytic activation during proteasome assembly

a, Molecular model of Ump1 from pre-15S (PDB: 7LS6) and the β3-D205Δ preholoproteasome. The first and last resolved residues are shown. b, Overlay of the two models, showing no significant conformational changes.
