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

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 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
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

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
