Protein
Gamma-glutamyl hydrolase
Function
Hydrolyzes the polyglutamate sidechains of pteroylpolyglutamates. Progressively removes gamma-glutamyl residues from pteroylpoly-gamma-glutamate to yield pteroyl-alpha-glutamate (folic acid) and free glutamate. May play an important role in the bioavailability of dietary pteroylpolyglutamates and in the metabolism of pteroylpolyglutamates and antifolates. Exhibits either endo- or exopeptidase activity depending upon the tissue of origin. When secreted, it acts primarily as an endopeptidase (By similarity).
Similarity
Belongs to the peptidase C26 family.
