S-nitrosoglutathione (GSNO, 50 microM) inhibited the initial rate of thrombin-catalyzed human and bovine fibrinogen polymerization by approximately 50% to 68% respectively. Inhibition was also observed with other structurally varied S-nitrosothiols (RSNOs) including sugar derivatives of S-nitroso-N-acetylpenicillamine (SNAP). The fact that the same concentration of GSNO had no effect on thrombi...
Is Their Quantity of No Relevance? To the Editor: Similarity of results is the most appropriate criterion to assess agreement between methods and clinical measurements.1 Reference intervals of a biochemical parameter are of particular importance for the definition of pathological conditions and the judgment of therapy success by pharmacological, nutritional, or physical measures. In this contex...
The rat alpha 1-1 glutathione S-transferase (GST) contains a single, non-essential tryptophan and only 8 tyrosines in each subunit. One of these tyrosines, Tyr-9, hydrogen bonds to the substrate glutathione and stabilizes the nucleophilic thiolate anion. Two mutant proteins that allow for the spectrocopic determination of the pKa of this catalytic residue have been constructed. The W21F mutant ...
