The proteasomal AAA<sup>+</sup>-ATPase unfolds substrates into the core particle, where proteolysis takes place. Applying single-particle cryo-electron microscopy and image classification to samples in the presence of different nucleotides and nucleotide analogs, we were able to observe four distinct conformational states. In a hitherto unobserved state (s4) the gate of the core particle is open. The resolution of the four conformers allowed for the construction of atomic models of the AAA<sup>+</sup>-ATPase module as it progresses through the functional cycle.}, keywords = {}, note = {}, url = {https://mediatum.ub.tum.de/1364110}, }
