It can synthesize various γ-glutamyl compounds,such as the L-γ-glutamyl-valine,improve its bitter taste,enhanced solubility of the L-γ-glutamyl-cystine,and increased theanine of biological activity.

Objective To explore the mechanism of traditional Chinese medicine(TCM) treatment according to syndrome differentiation in treating chronic obstructive pulmonary disease(COPD) by observing the changes of nuclear factor-κB(NF-κB) and γ-glutamylcysteine synthetase(γ-GCS) expression levels in rats.

Objective To explore the regulation of peroxisome proliferator-activated receptor γ coactivator 1α(PGC-1α) and NF-E2-related factor 2(Nrf2) on expression of γ-glutamylcysteine synthetase(γ-GCS),and their roles in chronic obstructive pulmonary disease(COPD).

Preparation of monoclonal antibody against γ-glutamyltransferase of primary hepatic cancer tissue strongly bound to datura stramonim(DSA) lectin and establishment of ELISA method;

Elevation and clinical significance of serum γ-glutamyltransferase in adult mycoplasma pneumoniae pneumonia;

Objective To determine the role and related mechanism of restraint stress on cancerogenesis by investigating the hepatocarcinogenesis, the concentration of γ-glutamyltransferase in the sera, DNA content and ploidy in hepatocytes.
