E-304

This enzyme is responsible for the first step in ubiquitin-protein isopeptide bond formation, by forming a high-energy thioester bond with ubiquitin. The ubiquitin is activated by first adenylating with ATP its C-terminal glycine residue (Gly76) and thereafter linking this residue to the side chains of a cysteine residue in UBE1, yielding an ubiquitin-UBE1 thiolester and free AMP and PPi. The activated ubiquitin is then transferred to a lysine of the targeted protein via the E2-E3 conjugation cascade.

E-308

Also known as: UBA7

This E1 is responsible for the first step in ISG15-protein isopeptide bond formation. The enzyme catalyzes the activation of the C-terminal carboxyl group of ISG15 by forming a high-energy thioester bond in an ATP-dependent manner. The activated ISG15 is then transferred to UbcH8 and subsequently to lysine groups of target proteins via this thiolester conjugation cascade. The E1 enzyme is a critical component for the initiation of any in vitro conjugation reactions.
