Gamma-glutamyl hydrolase

Gamma-glutamyl hydrolase is an enzyme that catalyses the following chemical reaction:

This lysosomal or secreted, thiol-dependent peptidase, most active at acidic pH.

In humans, gamma-glutamyl hydrolase is encoded by the GGH gene. This gene catalyzes the hydrolysis of folylpoly-gamma-glutamates and antifolylpoly-gamma-glutamates by the removal of gamma-linked polyglutamates and glutamate.
