Crystal structure of the yeast 20S proteasome in complex with bortezomib
Structural highlights
FunctionPSA2_YEAST The proteasome degrades poly-ubiquitinated proteins in the cytoplasm and in the nucleus. It is essential for the regulated turnover of proteins and for the removal of misfolded proteins. The proteasome is a multicatalytic proteinase complex that is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. It has an ATP-dependent proteolytic activity. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThe dipeptide boronic acid bortezomib, also termed VELCADE, is a proteasome inhibitor now in use for the treatment of multiple myeloma, and its use for the treatment of other malignancies is being explored. We determined the crystal structure of the yeast 20S proteasome in complex with bortezomib to establish the specificity and binding mode of bortezomib to the proteasome's different catalytically active sites. This structure should enable the rational design of new boronic acid derivatives with improved affinities and specificities for individual active subunits.
