HECT-type E3 ubiquitin transferase
Cat No.
EXWM-2300
Description
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 ε-amino group of an L-lysine residue of the acceptor protein.
Form
Liquid or lyophilized powder
Enzyme Commission Number
Storage

Synonyms
HECT E3 ligase (misleading); ubiquitin transferase HECT-E3
Reaction
S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine + [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-cysteine + N6-ubiquitinyl-[acceptor protein]-L-lysine (overall reaction); (1a) S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine + [HECT-type E3 ubiquitin transferase]-L-cysteine = [E2 ubiquitin-conjugating enzyme]-L-cysteine + S-ubiquitinyl-[HECT-type E3 ubiquitin transferase]-L-cysteine; (1b) S-ubiquitinyl-[HECT-type E3 ubiquitin transferase]-L-cysteine + [acceptor protein]-L-lysine = [HECT-type E3 ubiquitin transferase]-L-cysteine + N6-ubiquitinyl-[acceptor protein]-L-lysine
