Structural highlights

1fnt is a 20 chain structure with sequence from Saccharomyces cerevisiae. The December 2004 RCSB PDB Molecule of the Month feature on Ubiquitin by David S. Goodsell is 10.2210/rcsb_pdb/mom_2004_12. The October 2013 RCSB PDB Molecule of the Month feature on Proteasome by David Goodsell is 10.2210/rcsb_pdb/mom_2013_10. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

PSA1_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.
