Protein Ubiquitination Analysis Ubiquitin is an about 8.5 kDa polypeptide consisting of 76 amino acids that is appended to the ε-NH2 of lysine in target proteins via the C-terminal glycine of ubiquitin. Following an initial monoubiquitination event, the formation polyubiquitinated proteins are then recognized by the 26S proteasome that catalyzes the degradation of the ubiquitinated protein and the recycling of ubiquitin. of a ubiquitin polymer may occur, and
