Ubiquitin-Like Protein-Specific Protease Activity

Small Conjugating Protein-Specific Isopeptidase Activity

Catalysis of the hydrolysis of peptide or isopeptide bonds within small proteins such as ubiquitin or ubiquitin-like proteins (e.g. APG8, ISG15, NEDD8, SUMO), or between the small protein and a larger protein to which it has been conjugated.
