A series of enzymatic rate assays are described. The assays are based on coumarin derivatives that are fluorogenic substrates for the enzymes dipeptidase IV, aminopeptidase N, alkaline phosphatase, and gamma-glutamyltransferase. These simple assays are rapid and offer improved sensitivity over

gamma-Glutamyl transpeptidase (gammaGTase) catalyzes the transfer of the gamma-glutamyl moiety of gamma-glutamyl-derived peptides, such as glutathione (gammaGlu-Cys-Gly), and anilides, such as gamma-glutamyl-7-amido-4-methylcoumarin (gammaGlu-AMC), to acceptor molecules, including water and various dipeptides. These acyl-transfer reactions all occur through a common acyl-enzyme

Activities and isoenzyme patterns of gamma-glutamyl transferase (GGT) were studied in serum samples from fifteen Bantu males suffering from primary hepatoma; the results were compared with those obtained from normal samples. Enzyme activities were significantly higher in hepatoma patients than

A new fluorometric assay was developed for the measurement of gamma-glutamyl transpeptidase (gamma-GTP). The assay utilizes as a substrate the synthetic compound 7-gamma-glutamylamido-4-methyl coumarin which is cleaved by gamma-GTP to yield the highly fluorescent product 7-amino-4-methyl coumarin. Optimal excitation and

In this electrophoretic procedure for measuring isoenzymes of gamma-glutamyltransferase, patterns obtained are highly reproducible and the analytical imprecision (CV) ranges from 1.10% to 6.17%. A cellulose acetate support is used, at 220 V for 40 min. Sharply resolved isoenzyme bands
