Term Name: ubiquitin-protein transferase activity
Synonyms: E2, E3, ubiquitin conjugating enzyme activity, ubiquitin ligase activity, ubiquitin protein ligase activity, ubiquitin protein-ligase activity, ubiquitin-conjugating enzyme activity
Definition: Catalysis of the transfer of ubiquitin from one protein to another via the reaction X-Ub + Y = Y-Ub + X, where both X-Ub and Y-Ub are covalent linkages.
