The novel proteolytic mechanism of the 20S proteasome from T. acidophilum has been investigated by X-ray crystallography using small-molecule inhibitors and substrate analogues. The 20S proteasome degrades unfolded substrates into small peptides of a defined length. Calpain inhibitor II, chymostatin
