Abstract
RING and U-box ubiquitin ligases promote ubiquitin (Ub) transfer by priming Ub-conjugated E2 in a closed conformation to optimize the thioester bond for nucleophilic attack by substrate lysine. Here, we describe a single-turnover lysine discharge assay for direct assessment of the activity of any RING/U-box E3-E2~Ub complex.Entities:
