Bacteriol. 182:1680-1692(2000). CC -!- FUNCTION: The proteasome is a multicatalytic proteinase complex CC which is characterized by its ability to cleave peptides with Arg, CC Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or CC slightly basic pH. CC -!- CATALYTIC ACTIVITY: Cleavage of peptide bonds with very broad CC specificity. CC -!- SUBUNIT: Composed of two subunits, alpha and beta. The complex is CC formed of four rings. The two outer rings are each composed of CC seven alpha subunits. The two inner rings are each composed of CC seven beta subunits (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm. CC -!- SIMILARITY: Belongs to the peptidase T1A family.
