Function and Biology Details
Reactions catalysed:
ATP + H(2)O = ADP + phosphate
Peptidylproline (omega=180) = peptidylproline (omega=0)
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).
