In this paper we compare the measurement of catalytic activity concentrations of gamma-glutamyltransferase with the non-carboxylated and the carboxylated substrate in preparations of different origin. Fresh human sera, commercial test sera and preparations of gamma-glutamyltransferase purified from human liver, porcine

Two isozymes of gamma-glutamyltranspeptidase, GGT-A and GGT-B, were purified to electrophoretic homogeneity from a culture broth of Bacillus subtilis TAM-4, which produces poly(gamma-glutamic acid) (PGA) de novo. GGT-A was composed of three subunits with molecular weights of 23,000 (I), 39,000
The effect of thyroid hormone administration on liver glutathione (GSH) content and gamma-glutamyltransferase activity in the isolated perfused liver was studied for a period of 1-7 days in fed rats following a single dose of 0.1 mg 3,5,3'-L-triiodothyronine (T3)/kg. T3
European journal of biochemistry, 256(2), 297-302 (1998-10-06)
A new enzyme from Hirudo medicinalis capable of splitting gamma-glutamyl-p-nitroanilide and Glu--Lys-(N6-gamma-glutamyllysine) (isopeptidic bond between the epsilon-amino group of lysine and the gammacarboxylic group of glutamic acid) isopeptide bonds was purified. The protein was partially sequenced at the amino acid
