Ubikvitin-proteinska ligaza (EC 6.3.2.19, ubikvitin-aktivirajući enzim) je enzim sa sistematskim imenom ubikvitin:protein-lizin N-ligaza (formira AMP).[1][2][3][4] Ovaj enzim katalizuje sledeću hemijsku reakciju
- ATP + ubikvitin + protein lizin AMP + difosfat + protein N-ubikvitilizin
Ubikvitin je vezan za ovaj protein peptidnom vezom između C-terminalnog glicina ubikvitina i epsilon-amino grupa lizinskih ostataka proteina.
