obsolete sumoylated E2 ligase complex (obsolete GO:1990356)
OBSOLETE. A protein complex consisting of a SUMO (small ubiquitin-related modifier) protein bound to a SUMO-conjugating E2 ligase. Sumoylation of the E2 ligase is an intermediate step required for the formation of covalent bonds between a SUMO protein and its ultimate protein target. SUMO is transferred to the E2 ligase by a SUMO-activating E1 enzyme. Sumoylation of the target protein is either facilitated directly by the sumoylated E2 ligase or aided by an optional E3 ligase.
