ENZYME entry: EC 3.4.19.12

Accepted Name
Ubiquitinyl hydrolase 1.
Alternative Name(s)
Ubiquitin C-terminal hydrolase.
Ubiquitin carboxyl-terminal hydrolase.
Ubiquitin thiolesterase.
Reaction catalysed
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)
Comment(s)
  • Links to polypeptides smaller than 60 residues are hydrolyzed more readily than those to larger polypeptides.
  • Isoforms exist with quantitatively different specificities among the best known being UCH-L1 and UCH-L3, major proteins of the brain of mammals.
  • Inhibited by ubiquitin aldehyde (in which Gly76 is replaced by aminoacetaldehyde).
  • Belongs to peptidase family C12.
