Structure Motif Annotation: Mechanism and Catalytic Site Atlas M-CSA Database Homepage

Chains	Enzyme Name	Description	Catalytic Residues
B	gamma-glutamyl hydrolase M-CSA #747	gamma-glutamyl hydrolase is a lysosomal or secreted thiol-dependent peptidase most active at acidic pH that catalyses the cleavage of the gamma-glutamyl chain of folylpoly-gamma-glutamyl. Human gamma-glutamyl hydrolase (hGH) catalyses the hydrolysis of the gamma-linked polyglutamate chain of folyl- or antifolyl polyglutamates, releasing shorter chains of polyglutamates and diglutamates or glutamic acid.
