ENZYME entry: EC 3.4.19.13

Accepted Name
Glutathione hydrolase.
Alternative Name(s)
Gamma-glutamyltranspeptidase.
Glutathionase.
Reaction catalysed
Glutathione + H(2)O <=> L-cysteinylglycine + L-glutamate
Comment(s)
  • This protein also has EC 2.3.2.2 activity.
  • The enzyme consists of two chains that are created by the proteolytic cleavage of a single precursor polypeptide.
  • The N-terminal L-threonine of the C-terminal subunit functions as the active site for both the cleavage and the hydrolysis reactions.
  • The human enzyme also hydrolyzes oxidized glutathione and leukotriene C4 with similar efficiency, while the mouse enzyme does not.
