Priming and extending: an UbcH5/Cdc34 E2 handoff mechanism for polyubiquitination on a SCF substrate
We describe a mechanistic model of polyubiquitination by the SCF(β(TrCP2)) E3 ubiquitin (Ub) ligase using human IκBα as a substrate. Biochemical reconstitution experiments revealed that the polyubiquitination of IκBα began with the action of the UbcH5 E2 Ub conjugating enzyme, transferring a single...
