FRET di-ubiquitination relies on Ub-substrate fusion, which can be implemented using either one of the two validated strategies. Method one is the use of recombinant substrate-Ub fusion, applicable to all substrate peptides that can bind to E3. Method two is a chemo-enzymatic ligation approach that employs synthetic chemistry to fuse Ub with a substrate peptide containing desired modification. Taken together, our new FRET-based di-ubiquitination system provides a timely technology of potential to advance both basic research and t
