Secondary Accession Numbers
  • 8804
  • HMDBP04399
Name Gamma-glutamyl hydrolase
Synonyms
  1. Conjugase
  2. GH
  3. Gamma-Glu-X carboxypeptidase
Gene Name GGH
Protein Type Enzyme
Biological Properties
General Function Involved in catalytic activity
Specific 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.
Pathways
  • Folate biosynthesis
  • Folate malabsorption, hereditary
  • Methotrexate Action Pathway
  • Methylenetetrahydrofolate Reductase Deficiency (MTHFRD)
  • One carbon pool by folate
Reactions
