CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Thiol-dependent hydrolysis of ester, thioester, amide, peptide
CC         and isopeptide bonds formed by the C-terminal Gly of ubiquitin (a 76-
CC         residue protein attached to proteins as an intracellular targeting
CC         signal).; EC=3.4.19.12;
CC   -!- SIMILARITY: Belongs to the peptidase C19 family. {ECO:0000305}.
