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 + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate.
