EOG88WFGC GO:0000502 6/87 proteasome complex cellular_component "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." [GOC:rb, http://en.wikipedia.org/wiki/Proteasome] EOG88WFGC GO:0043161 1/87 proteasome-mediated ubiquitin-dependent protein catabolic process biological_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 ubiquitin, and mediated by the proteasome." [GOC:go_curators] EOG88WFGC GO:0008541 1/87 proteasome regulatory particle, lid subcomplex cellular_component "The subcomplex of the proteasome regulatory particle that forms the peripheral lid, which is added on top of the base subcomplex." [GOC:rb] EOG88WFGC GO:0005838 1/87 proteasome regulatory particle cellular_component "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." [GOC:mtg_sensu, GOC:rb] EOG88WFGC GO:0006508 1/87 proteolysis biological_process "The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds."
