Enzyme Information
| 2.3.2.26 | HECT-type E3 ubiquitin transferase. based on mapping to UniProt Q9VVI3 S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine + [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-cysteine + N(6)- ubiquitinyl-[acceptor protein]-L-lysine. -!- In the first step the enzyme transfers ubiquitin from the E2 ubiquitin-conjugating enzyme (EC 2.3.2.23) to a cysteine residue in its HECT domain (which is located in the C-terminal region), forming a thioester bond. -!- In a subsequent step the enzyme transfers the ubiquitin to an acceptor protein, resulting in the formation of an isopeptide bond between the C-terminal glycine residue of ubiquitin and the epsilon- amino group of an L-lysine residue of the acceptor protein. -!- Cf. EC 2.3.2.27 and EC 2.3.2.31. |
