Salinosporamide A (IMAGE) Technical University of Munich (TUM) Caption Snapshots of a biochemical process -- obtained through X-ray crystallography -- provide insights that could guide development of tailored anti-cancer drugs. Researchers at the Technische Universitaet Muenchen and Nereus Pharmaceuticals have determined in detail how the bacteria-derived molecule Salinosporamide A disables the intracellular waste-processing plants called proteasomes. The researchers compare the mechanism to a key that breaks off in a lock. Credit TUM Dept. of Biochemistry and Nereus Pharmaceuticals.
