Natl. Acad. Sci. U.S.A. 109:14870-14875(2012). CC -!- FUNCTION: The proteasome degrades poly-ubiquitinated proteins in CC the cytoplasm and in the nucleus. It is essential for the CC regulated turnover of proteins and for the removal of misfolded CC proteins. The proteasome is a multicatalytic proteinase complex CC that 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. It has an ATP-dependent proteolytic activity. CC PRE3 and PRE4 are necessary for the peptidyl-glutamyl-peptide- CC hydrolyzing activity. CC -!- FUNCTION: This subunit is necessary for the peptidylglutamyl- CC peptide hydrolyzing activity. CC -!- CATALYTIC ACTIVITY: Cleavage of peptide bonds with very broad CC specificity. CC -!- SUBUNIT: The 26S proteasome consists of a 20S proteasome core and CC two 19S regulatory subunits. The 20S proteasome core is composed CC of 28 subunits that are arranged in four stacked rings, resulting CC in a barrel-shaped structure. The two end rings are each formed by CC seven alpha subunits, and the two central rings are each formed by CC seven beta subunits. The catalytic chamber with the active sites CC is on the inside of the barrel. {ECO:0000269|PubMed:20227375}. CC -!- SUBCELLULAR LOCATION: Cytoplasm. Nucleus. CC -!- MISCELLANEOUS: The side chain of Thr-20 acts as nucleophile, and CC the N-terminal amino group acts as proton acceptor. CC -!- MISCELLANEOUS: Present with 7250 molecules/cell in log phase SD CC medium. {ECO:0000269|PubMed:14562106}. CC -!- SIMILARITY: Belongs to the peptidase T1B family. CC {ECO:0000255|PROSITE-ProRule:PRU00809}.
