摘要：
The proteasome 19S particle processes ubiquitinated substrates, unfolds the polypeptides and translocates them to the 20S core particle. Now cryo-EM analyses of the yeast proteasome in the presence of substrate show the 19S in an active conformation, with the AAA+ ring forming a wider central channel aligned with the 20S pore and the essential deubiquitinase Rpn11 positioned right above it.
