| molecular function |
| | GO:0008234 | | cysteine-type peptidase activity | | Catalysis of the hydrolysis of peptide bonds in a polypeptide chain by a mechanism in which the sulfhydryl group of a cysteine residue at the active center acts as a nucleophile. |
| | GO:0016787 | | hydrolase activity | | Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3. |
| | GO:0008233 | | peptidase activity | | Catalysis of the hydrolysis of a peptide bond. A peptide bond is a covalent bond formed when the carbon atom from the carboxyl group of one amino acid shares electrons with the nitrogen atom from the amino group of a second amino acid. |
| | GO:0004843 | | thiol-dependent ubiquitin-specific protease activity | | Catalysis of the thiol-dependent hydrolysis of a peptide bond formed by the C-terminal glycine of ubiquitin and another protein. |
| | GO:0036459 | | thiol-dependent ubiquitinyl hydrolase activity | | Catalysis of the thiol-dependent hydrolysis of an ester, thioester, amide, peptide or isopeptide bond formed by the C-terminal glycine of ubiquitin. |
| biological process |
| | GO:1901799 | | negative regulation of proteasomal protein catabolic process | | Any process that stops, prevents or reduces the frequency, rate or extent of proteasomal protein catabolic process. |
| | GO:0016579 | | protein deubiquitination | | The removal of one or more ubiquitin groups from a protein. |
| | GO:0006508 | | proteolysis | | The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds. |
| | GO:0032434 | | regulation of proteasomal ubiquitin-dependent protein catabolic process | | Any process that modulates the frequency, rate or extent of the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of ubiquitin, and mediated by the proteasome. |
| | GO:0006511 | | ubiquitin-dependent protein catabolic process | | The chemical reactions and pathways resulting in the breakdown of a protein or peptide by hydrolysis of its peptide bonds, initiated by the covalent attachment of a ubiquitin group, or multiple ubiquitin groups, to the protein. |
| cellular component |
| | GO:0000502 | | proteasome complex | | A large multisubunit complex which catalyzes protein degradation, found in eukaryotes, archaea and some bacteria. In eukaryotes, this complex consists of the barrel shaped proteasome core complex and one or two associated proteins or complexes that act in regulating entry into or exit from the core. |
| | GO:0005838 | | proteasome regulatory particle | | A multisubunit complex, which caps one or both ends of the proteasome core complex. This complex recognizes and unfolds ubiquitinated proteins, and translocates them to the proteasome core complex. |
