Function
- Function:
- The proteasome is a multicatalytic proteinase complex which 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. The proteasome has an ATP-dependent proteolytic activity. This subunit is involved in antigen processing to generate class I binding peptides.
- Catalytic Activity:
- Cleavage of peptide bonds with very broad specificity.
- Active Site:
- ACT_SITE 40 40 Nucleophile.
