SUMO (small ubiquitin-related modifier) proteins are ∼10-kD polypeptides that function as reversible post-translational protein modifiers. They form isopeptide bonds with ɛ-amino groups of acceptor ...
Sumoylation is a post-translational modification process. It is analogous to ubiquitylation in terms of the reaction scheme and enzyme classes used, but rather than conjugation by ubiquitin, ...
