The hydrolysis of a series of esters of benzoyl-L-arginine and glycylglycine by papain has been examined in mixtures of water with various alcohols in the pH range of 5 to 6. The presence of straight chain alcohols resulted in an apparent inhibition of acid release. It was shown that this inhibition could, in part, be accounted for by papain-catalyzed transesterification reactions between the v...
The ligand N-(2-hydr-oxy-3-methoxy-benzyl-idene)glycylglycine (H(3)L), a Schiff base derived from glycylglycine and 3-methoxy-salicylaldehyde, was used in the synthesis of a new organic-inorganic coordination complex, [Mn(H(2)O)(6)][Cu(C(12)H(11)N(2)O(5))](2)·6H(2)O. The Mn(II) atom is located on an inversion center and is coordinated to six water mol-ecules in a slightly distorted octa-hedral ...
The title compound, C(12)H(13)NO(3), was prepared by the nucleophilic substitution reaction of acryloyl chloride with glycylglycine. In the crystal structure, inter-molecular N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
Residual dipolar couplings (RDCs) observed between nuclear spins in molecules in partially oriented media have become a valuable source of information for NMR spectroscopists seeking to structurally characterize biological macromolecules. Examination of the form of the direct (D) and indirect (J) nuclear spin-spin coupling Hamiltonians indicates that all observed RDCs contain an unknown contrib...
S-nitrosoglutathione (GSNO) involved in storage and transport of nitric oxide ((•)NO) plays an important role in vascular homeostasis. Breakdown of GSNO can be catalyzed by γ-glutamyltransferase (GGT). We investigated whether vascular GGT influences the vasorelaxant effect of GSNO in isolated rat aorta. Histochemical localization of GGT and measurement of its activity were performed by using ch...
