GGH - Gamma-Glutamyl Hydrolase | Elisa - Clia - Antibody - Protein

Family main features

Background:

Gamma-Glutamyl Hydrolase (GGH) is an essential enzyme involved in the metabolism of folates, critical for various cellular processes such as DNA synthesis, repair, and methylation. This enzyme specifically hydrolyzes polyglutamylated folates, converting them into monoglutamate forms, which are crucial for their cellular uptake and function. GGH activity ensures the maintenance of adequate intracellular folate levels, thereby supporting essential biochemical pathways. It is ubiquitously expressed in various tissues, including the liver, kidney, and gastrointestinal tract, underlining its systemic role in folate metabolism.

GGH plays a significant role in pharmacology, especially in the context of antifolate drugs used in chemotherapy, such as methotrexate. By regulating the levels of polyglutamylated antifolates within cells, GGH can influence the efficacy and toxicity of these therapeutic agents. Variations in GGH expression or activity can significantly impact drug sensitivity and resistance in cancer cells, making it a focal point in cancer research.


Protein Structure

GGH is a lysosomal enzyme comprising approximately 318 amino acids. It includes an N-terminal signal peptide that directs the enzyme to lysosomes and a catalytic domain where the hydrolysis of gamma-glutamyl bonds occurs. The enzyme's active site contains conserved residues crucial for its hydrolase activity. Structural studies have revealed that the enzyme operates via a mechanism that involves substrate binding, catalysis, and product release, all facilitated by the specific arrangement of amino acids in the active site.


Classification and Subtypes

GGH belongs to the family of hydrolases, specifically acting on carbon-nitrogen bonds other than peptide bonds in linear amides, classified under EC 3.4.19.9. While GGH itself does not have well-defined subtypes, its homologs and isoforms in different species serve similar functions in folate metabolism. Genetic variations and alternative splicing events may lead to different isoforms, potentially altering the enzyme's function or regulation.


Function and Biological Significance

The primary function of GGH is to hydrolyze polyglutamylated folates into their monoglutamate forms, which are necessary for cellular uptake and utilization. This enzymatic activity is pivotal for maintaining folate homeostasis and supporting DNA synthesis, repair, and methylation processes. GGH also regulates the intracellular concentration of folate derivatives, thereby influencing one-carbon metabolism pathways.

In cancer therapy, GGH modulates the effectiveness of antifolate drugs by controlling their polyglutamylation status. Enhanced GGH activity can lead to drug resistance by decreasing the retention of active drug forms within cells. Conversely, inhibiting GGH can increase drug efficacy by maintaining higher intracellular concentrations of active antifolates.


Clinical Issues

Alterations in GGH activity are associated with several clinical conditions. Overexpression of GGH in cancer cells can lead to resistance to antifolate chemotherapy, presenting a significant challenge in treatment. Conversely, reduced GGH activity can cause folate deficiency, impairing DNA synthesis and repair, and potentially leading to developmental disorders such as neural tube defects.

Inhibitors of GGH are being investigated as potential adjuvant therapies in cancer treatment to enhance the efficacy of antifolate drugs. Additionally, genetic polymorphisms in the GGH gene may serve as biomarkers for predicting patient response to folate-based treatments and susceptibility to certain diseases.


Summary

Gamma-Glutamyl Hydrolase (GGH) is a critical enzyme in folate metabolism, essential for DNA synthesis and repair. Its role in hydrolyzing polyglutamylated folates ensures proper cellular uptake and function of folates. GGH activity significantly impacts the effectiveness of antifolate drugs in cancer therapy, making it a target for enhancing therapeutic outcomes. Alterations in GGH expression or function are associated with various clinical conditions, highlighting its importance in both normal physiology and disease states.
