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 CC ARG, PHE, TYR, LEU, AND GLU ADJACENT TO THE LEAVING GROUP AT CC NEUTRAL OR SLIGHTLY BASIC PH. CC -!- CATALYTIC ACTIVITY: CLEAVAGE AT 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: CYTOPLASMIC. CC -!- SIMILARITY: BELONGS TO PEPTIDASE FAMILY T1A; ALSO KNOWN AS THE CC PROTEASOME A-TYPE FAMILY.
