    GO:1990356    sumoylated E2 ligase complex    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.
    GO:0000795    synaptonemal complex    A proteinaceous scaffold found between homologous chromosomes during meiosis. It consists of 2 lateral elements and a central element, all running parallel to each other. Transverse filaments connect the lateral elements to the central element.
