CC -!- FUNCTION: Catalyzes the covalent attachment of ubiquitin to other CC proteins. Mediates the selective degradation of short-lived and CC abnormal proteins. CC -!- CATALYTIC ACTIVITY: ATP + ubiquitin + protein lysine = AMP + CC diphosphate + protein N-ubiquityllysine. CC -!- PATHWAY: Protein modification; protein ubiquitination. CC -!- SUBUNIT: Interacts with TUL1. CC -!- INDUCTION: By heat shock and cadmium. CC -!- PTM: The N-terminus is blocked. CC -!- MISCELLANEOUS: Present with 13500 molecules/cell in log phase SD CC medium. CC -!- SIMILARITY: Belongs to the ubiquitin-conjugating enzyme family.
