A strategy for the synthesis of dehydroalanine based diubiquitin activity probes is described. The site-specific introduction of dehydroalanine was achieved from diubiquitin bearing Cys residue near the scissile bond between two ubiquitins linked through Lys48, Lys63 or in a head to tail fashion. The probes were characterized for their activities with various deubiquitinases, which open new opportunities in studying deubiquitinases in various settings.
