Asymmetric Unit(hide GO term definitions)
Chain A,B,D,F   (UBR1_YEAST | P19812)
molecular function
    GO:0016874    ligase activity    Catalysis of the joining of two substances, or two groups within a single molecule, with the concomitant hydrolysis of the diphosphate bond in ATP or a similar triphosphate.
    GO:0046872    metal ion binding    Interacting selectively and non-covalently with any metal ion.
    GO:0005515    protein binding    Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
    GO:0061630    ubiquitin protein ligase activity    Catalysis of the transfer of ubiquitin to a substrate protein via the reaction X-ubiquitin + S -> X + S-ubiquitin, where X is either an E2 or E3 enzyme, the X-ubiquitin linkage is a thioester bond, and the S-ubiquitin linkage is an amide bond: an isopeptide bond between the C-terminal glycine of ubiquitin and the epsilon-amino group of lysine residues in the substrate or, in the linear extension of ubiquitin chains, a peptide bond the between the C-terminal glycine and N-terminal methionine of ubiquitin residues.
    GO:0004842    ubiquitin-protein transferase activity    Catalysis of the transfer of ubiquitin from one protein to another via the reaction X-Ub + Y --> Y-Ub + X, where both X-Ub and Y-Ub are covalent linkages.
    GO:0008270    zinc ion binding    Interacting selectively and non-covalently with zinc (Zn) ions.
biological process
    GO:0006513    protein monoubiquitination    Addition of a single ubiquitin group to a protein.
    GO:0000209    protein polyubiquitination    Addition of multiple ubiquitin groups to a protein, forming a ubiquitin chain.
    GO:0016567    protein ubiquitination    The process in which one or more ubiquitin groups are added to a protein.
    GO:0090089    regulation of dipeptide transport    Any process that modulates the rate, frequency or extent of dipeptide transport. Dipeptide transport is the directed movement of a dipeptide, a combination of two amino acids by means of a peptide (-CO-NH-) link, into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
    GO:1990116    ribosome-associated ubiquitin-dependent protein catabolic process    The chemical reactions and pathways resulting in the breakdown of a protein or peptide encoded by an aberrant message and associated with a stalled ribosome. Degradation is initiated by the covalent attachment of a ubiquitin group, or multiple ubiquitin groups, to the ribosome-associated protein.
    GO:0030433    ubiquitin-dependent ERAD pathway    The series of steps necessary to target endoplasmic reticulum (ER)-resident proteins for degradation by the cytoplasmic proteasome. Begins with recognition of the ER-resident protein, includes retrotranslocation (dislocation) of the protein from the ER to the cytosol, protein ubiquitination necessary for correct substrate transfer, transport of the protein to the proteasome, and ends with degradation of the protein by the cytoplasmic proteasome.
    GO:0071629    ubiquitin-dependent catabolism of misfolded proteins by cytoplasm-associated proteasome    The chemical reactions and pathways resulting in the breakdown of misfolded proteins in the cytoplasm, which are targeted to cytoplasmic proteasomes for degradation.
    GO:0071596    ubiquitin-dependent protein catabolic process via the N-end rule pathway    The chemical reactions and pathways resulting in the breakdown of a protein or peptide covalently tagged with ubiquitin, via the N-end rule pathway. In the N-end rule pathway, destabilizing N-terminal residues (N-degrons) in substrates are recognized by E3 ligases (N-recognins), whereupon the substrates are linked to ubiquitin and then delivered to the proteasome for degradation.
cellular component
    GO:0005737    cytoplasm    All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
    GO:0008540    proteasome regulatory particle, base subcomplex    The subcomplex of the proteasome regulatory particle that directly associates with the proteasome core complex.
    GO:0000151    ubiquitin ligase complex    A protein complex that includes a ubiquitin-protein ligase and enables ubiquitin protein ligase activity. The complex also contains other proteins that may confer substrate specificity on the complex.
