Ubiquitination is initiated by transfer of ubiquitin (Ub) from a ubiquitin-activating enzyme (E1) to a ubiquitin-conjugating enzyme (E2), producing a covalently linked intermediate (E2-Ub) 1 . Ubiquitin ligases (E3s) of the 'really interesting new gene' (RING) class recruit E2-Ub via their RING domain and then mediate direct transfer of ubiquitin to substrates 2 . By contrast, 'homologous to E6-AP carboxy ... [more]

Throughput

• High Throughput

Additional Notes

• bait proteins from cell lysate were identified by mass spec in two separate experiments as proteins covalently attached via an aborted transthiolation attempt to a suicide substrate composed of both the E2s UBE2D2 and UBE2L3 attached in vitro to a tagged modified ubiquitin
