gamma-glutamyltransferase

(redirected from G-glutamyltransferase)

γ-glu·tam·yl·trans·fer·ase

(glū-tam'il-trans'fĕr-ās),
An enzyme that catalyzes the transfer of a γ-glutamyl group from a γ-glutamyl peptide (usually glutathione) to another peptide, certain amino acids, or water; a deficiency of this enzyme will result in glutathionuria.
Synonym(s): γ-glutamyl transpeptidase

gamma-glutamyltransferase (GGT)

an enzyme that appears in the serum of patients with several types of liver or gallbladder disorders, including drug hepatotoxicity, biliary tract obstruction, alcohol-induced liver disease, and liver carcinoma. Normal adult (after 45 years of age) GGT blood levels are 8 to 38 U/L.
