WebJan 23, 2024 · 5. By definition, an E1 reaction is a Unimolecular Elimination reaction. This means the only rate determining step is that of the dissociation of the leaving group to form a carbocation. Since E2 is bimolecular and the nucleophilic attack is part of the rate determining step, a weak base/nucleophile disfavors it and ultimately allows E1 to ...

WebUbiquitination is catalyzed by three enzymes, E1, E2, and E3. E1 is a ubiquitin-activating enzyme that loads ubiquitin in an ATP-dependent manner. E1 transfers ubiquitin to E2, which is a ubiquitin-conjugating enzyme. E3, a ubiquitin ligase, is responsible for placing the ubiquitin moiety to the target protein. In humans, there are 500–1000 ...
