Ubiquitin is covalently attached via an enzymatic cascade to target proteins through an isopeptide bond between the C-terminus of ubiquitin and a lysine residue of the acceptor substrate [1]. Assembly of a chain of >=4 ubiquitins linked together via Lys48 of ubiquitin marks cellular proteins for degradation by the 26S proteasome [2-3]. The 26S proteasome is a 2.5 megadalton macromolecular protein complex that comprises two distinct subparticles: the 19S cap regulatory particle (RP) and the 20S core |
