In the News (Wed 23 Dec 09)

  
  Identity of maleate-stimulated glutaminase with gamma-glutamyl transpeptidase in rat kidney.
Gamma-Glutamyl transpeptidase was purified from rat kidney by a procedure involving Lubrol extraction, acetone precipitation, ammonium sulfate fractionation, treatment with bromelain, and column chromatography on DEAE-cellulose and Sephadex G-100.
The purified transpeptidase (enzyme III) is similar to the phosphate-independent maleate-stimulated glutaminase preparation obtained from rat kidney by Katunuma and colleagues with respect to amino acid and carbohydrate content, apparent molecular weight, and relative transpeptidase and maleate-stimulated "glutaminase" activities.
The studies on the ontogeny of gamma-glutamyl transpeptidase and other data are considered in relation to the proposal that this enzyme is involved in amino acid and peptide transport.

The most common laboratory measures classified as liver function tests (LFTs) include the enzyme tests (principally the serum aminotransferases, alkaline phosphatase, and gamma glutamyl transpeptidase), the serum bilirubin, and tests of synthetic function (principally the serum albumin concentration and prothrombin time).
The gamma glutamyl transpeptidase (GGT) test helps to detect liver and bile duct injury.
While some doctors use it in all people they suspect of having liver disease, others use it only to help explain the cause of other changes or if they suspect alcohol abuse.

The proteins synthesise cross-linked peptidoglycan from lipid intermediates, and contain a penicillin-sensitive transpeptidase carboxy-terminal domain.
The active site serine (residue 337 in) is conserved in all members of this family PUBMED:8605631.
