  • In contrast to ubiquitin, SUMO is not used to tag proteins for degradation.
  • Mature SUMO is produced when the last four amino acids of the C-terminus have been cleaved off to allow formation of an isopeptide bond between the C-terminal glycine residue of SUMO and an acceptor lysine on the target ....
