Protein

Ubiquitin-conjugating enzyme E2 19

Gene

UBC19

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Accepts the ubiquitin from the E1 complex and catalyzes its covalent attachment to other proteins. Part of the anaphase-promoting complex (APC). May have a key function during cell cycle and be involved in cyclin B1 degradation.1 Publication

Catalytic activityi

ATP + ubiquitin + protein lysine = AMP + diphosphate + protein N-ubiquityllysine.PROSITE-ProRule annotation
