Descriptions Names[Advanced Search]

The process by which a SUMO protein (small ubiquitin-related modifier) is conjugated to a target protein via an isopeptide bond between the carboxyl terminus of SUMO with an epsilon-amino group of a lysine residue of the target protein. Any process that modulates the frequency, rate or extent of the covalent alteration of one or more amino acid residues within a protein. A protein modification process by which one or more moieties of a small protein, such as ubiquitin or a ubiquitin-like protein, are covalently attached to a target protein. Any process that modulates the frequency, rate or extent of the addition of SUMO moieties to a protein. Any process that stops, prevents or reduces the frequency, rate or extent of the addition of SUMO moieties to a protein. Any process that stops, prevents or reduces the frequency, rate or extent of the chemical reactions and pathways involving a protein, occurring at the level of an individual cell. The covalent alteration of one or more amino acids occurring in proteins, peptides and nascent polypeptides (co-translational, post-translational modifications). Includes the modification of charged tRNAs that are destined to occur in a protein (pre-translation modification). Any process that stops, prevents or reduces the frequency, rate or extent of the covalent alteration of one or more amino acid residues within a protein. The covalent alteration of one or more amino acids occurring in a protein after the protein has been completely translated and released from the ribosome.
