Ubiquitin Chain Trimming Recycles the Substrate Binding Sites of the 26 S Proteasome and Promotes Degradation of Lysine 48-linked Polyubiquitin Conjugates
The 26 S proteasome possesses two distinct deubiquitinating activities. The ubiquitin (Ub) chain amputation activity removes the entire polyUb chain from the substrates. The Ub chain trimming activity progressively cleaves a polyUb chain from the distal end. The Ub chain amputation activity mediates...
