Function and Biology Details
Reactions catalysed:
Cleavage of peptide bonds with very broad specificity.
Thiol-dependent hydrolysis of ester, thioester, amide, peptide and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-residue protein attached to proteins as an intracellular targeting signal).
