Extended Data Fig. 5: The RP–CP interface in different states.
From: Cryo-EM structures and dynamics of substrate-engaged human 26S proteasome
a, Comparison of the RP–CP interface and RPT C-terminal tail insertions into the α-pockets of the CP in different states. The cryo-EM densities of the RP–CP interfaces are shown as a grey surface representation. The red dashed circles highlight the densities of the RPT C-terminal tails. b, Close-up views and comparison of the RPT C-tail densities superimposed with the atomic models in different states. The cryo-EM densities of the RPT C-tails are shown in blue mesh representation. The atomic models of the RPT C-tails are shown in stick representation. The CP structures are shown as grey cartoon representations.
