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
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

1. Crude salivary gland extract of the giant Amazon leech, Haementeria ghilianii, contains an inhibitor of plasma factor XIIIa. 2. The inhibitory agent was purified to homogeneity by anion-exchange, cation-exchange, gel-filtration and reverse-phase chromatography to yield a single band on

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 molecular mass of destabilase isolated from the medicinae leech Hirudo medicinalis was found to be equal to 12.3 kDa. A kinetic analysis of the sole presently known synthetic substrate, L-gamma-Glu-pNA, showed that the enzyme is relatively stable to heating
