A Tetrahedral Transition State at the Active Sites of the 20S Proteasome is Coupled to Opening of the α-Ring Channel

Intrinsic conformational transitions contribute to the catalytic action of many enzymes. Here we use a single-molecule approach to demonstrate how such transitions are linked to the catalytic sites of the eukaryotic proteasome, an essential protease of the ubiquitin pathway. The active sites of the...
