A probe for the ubiquitin-like protein Fubi led to the discovery of dual ubiquitin/Fubi C-terminal hydrolase activity in the deubiquitinase USP16 in addition to USP36, enabling structural characterization of this distinctive Ub/Ubl specificity, and revealed a synergistic role of USP16 in ribosomal protein maturation.
