Abstract:
Highlights? Identification of OTUB1 mutants with impaired ability to inhibit E2 enzymes ? Crystal structure of a ubiquitin-charged E2 bound to OTUB1 ? Molecular basis of Lys48-linked ubiquitin chain recognition by OTUB1 determined ? OTUB1 employs product inhibition mimicry to inhibit E2 enzymes
