The ubiquitination process is mediated sequentially by three classes of enzymes consisting of a Ub-activating enzyme E1, a Ub-conjugating enzyme E2, and a Ub ligase E3. Ub is first activated by E1 in an adenosine 5′-triphosphate (ATP)-dependent manner to form a thioester-linked E1‒Ub conjugate. The activated Ub is then delivered to an E2 enzyme via a transthiolation reaction. Finally, an E3 enzyme, which can bind both a substrate and an E2‒Ub conjugate, mediates the covalent linkage of Ub to the target protein as a tag. |
