Crystal structure of the human TRIM25 PRYSPRY domain


Function and Biology Details

Reactions catalysed:
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
ATP + [ISG15] + [protein]-lysine = AMP + diphosphate + [protein]-N-ISGyllysine
