2',3'-O-(2,4,6-trinitrophenyl)-8-azido-AMP and -ATP photolabel Lys-492 at the active site of sarcoplasmic reticulum Ca(2+)-ATPase.
2',3'-O-(2,4,6-trinitrophenyl)-8-azido (TNP-8N3)-AMP, -ADP, and -ATP bind tightly to the Ca(2+)-ATPase of skeletal muscle sarcoplasmic reticulum and become covalently attached on irradiation at alkaline pH, concomitant with inactivation of ATPase activity (Seebregts, C. J., and McIntosh, D. B. (1989) J. Biol. Chem. 264, 2043-2052). The ATPase is derivatized to the extent of 2-3 nmol/mg protein ...
متن کاملPhotoaffinity labeling of rotavirus VP1 with 8-azido-ATP: identification of the viral RNA polymerase.
Rotavirus single-shelled particles have several enzymatic activities that are involved with the synthesis of capped mRNAs both in vivo and in vitro. Because single-shelled particles must be structurally intact to carry out transcription, it has proven to be difficult to identify the protein within such particles that possesses associated RNA polymerase activity. One approach for characterizing ...
متن کاملPhotoaffinity labeling of rat liver carbamoyl phosphate synthetase I by 8-azido-ATP.
8-Azido-ATP has been found to serve as a photoaffinity label for two distinct ATP sites on rat liver carbamoyl phosphate synthetase I and to allow preliminary localization of these sites. In the dark, 8-azido-ATP acted as a competitive inhibitor with respect to ATP. Ultraviolet irradiation of carbamoyl phosphate synthetase I in the presence of 8-azido-ATP led to an irreversible loss of activity...
متن کامل2-Azido-2-deoxy-3,4-O-isopropylidene-2-C-methyl-d-talono-1,5-lactone
The relative stereochemistry of the title compound, C(10)H(15)N(3)O(5), was confirmed by the crystal structure determin-ation. The absolute configuration was determined from the use of d-lyxonolactone as the starting material. The six-membered ring adopts a boat conformation with the larger azide group, rather than the methyl group, in the bowsprit position. In the crystal structure, a bifurcat...
متن کامل(Azido-κN)[6-methoxy-2-(2-pyridylmethyliminomethyl)phenolato-κ3 N,N′,O 1]copper(II)
The title compound, [Cu(C(14)H(13)N(2)O(2))(N(3))], is a monomeric neutral complex with one unsymmetrical 6-meth-oxy-2-(2-pyridylmethyl-imino-meth-yl)phenolate Schiff base ligand and one azide ligand. The mol-ecules are connected by a combination of two π-π inter-actions [centroid-centroid distances 3.359 (3) and 3.378 (2) Å] and one C-H⋯N hydrogen bond into a two-dimensional supra-molecular ne...
