Adenine nucleotides in thrombocytes of birds
Cell Biochemistry and Function, 1984AbstractAnalysis of free nucleotide composition of both avian thrombocytes and pig platelets showed quantitative differences in the level of adenine nucleotides. 3H‐adenine taken up by turkey thrombocytes was metabolized mainly to adenine nucleotides was not released after thrombin action.

K channel interaction with adenine nucleotides
Journal of Molecular and Cellular Cardiology, 2005ATP-sensitive potassium (K(ATP)) channels are regulated by adenine nucleotides to convert changes in cellular metabolic levels into membrane excitability. Hence, elucidation of interaction of SUR and Kir6.x with adenine nucleotides is an important issue to understand the molecular mechanisms underlying the metabolic regulation of the K(ATP) channels ...

Abstract A new, dynamic cycling procedure for total adenine nucleotides (ATP + ADP + AMP) is described. This procedure permits the measurement of adenine nucleotides in TCA extracts of fresh or frozen blood samples without requiring the removal of TCA from extract.

Adenine nucleotides and ventricular fibrillation
Journal of Molecular and Cellular Cardiology, 1987The isolated perfused rat heart was used to study the influence of adenine nucleotides and their metabolites on vulnerability to ventricular fibrillation. In this model the incidence of ventricular arrhythmias after coronary artery ligation is determined by the extracellular K+ concentration; with perfusate K+ of 2.0 and 3.0 mmol/l hearts develop a ...

Measurement of adenine nucleotides in plasma
Luminescence, 2003AbstractThe goal of this study was to identify the most important variables affecting bioluminescent ATP, ADP and AMP measurements in plasma and to develop an assay that takes these variables into account. Blood samples were drawn from conscious dogs.

Adenine nucleotides of the stria vascularis
Archives of Oto-Rhino-Laryngology, 1979The levels of the adenine nucleotides ATP, ADP, and AMP in the stria vascularis were measured under normal conditions, and following various durations of ischemia. The concentrations of these compounds were used for the calculation of the adenylate energy charge, the energy status and the phosphorylation state of the stria. Following 10 min of ischemia

Reactions of Dysprosium with Adenine Nucleotides
Journal of Inorganic Biochemistry, 1988Dysprosium catalyzes a rapid hydrolysis of both ATP and ADP, at ambient temperatures, pH 7.0, where no hydroxide precipitates. The reactive complexes, at pH 6.7, were found to contain 2Dy:1ATP and 3Dy:2ADP. AMP forms an insoluble complex containing 1Dy:2AMP, which does not hydrolyze.

The adenine nucleotide translocator in apoptosis
Biochimie, 2002Alteration of mitochondrial membrane permeability is a central mechanism leading invariably to cell death, which results, at least in part, from the opening of the permeability transition pore complex (PTPC). Indeed, extended PTPC opening is sufficient to trigger an increase in mitochondrial membrane permeability and apoptosis.

Mechanisms of inhibition of adenine phosphoribosyltransferase by adenine nucleosides and nucleotides
Canadian Journal of Biochemistry, 1970Kinetic studies of the inhibition of adenine phosphoribosyltransferase by adenine 6′-deoxyallofuranoside and 2′-deoxyadenylate indicate that both compounds bind to free enzyme and to the enzyme–phosphoribosylpyrophosphate complex, although they bind with different relative affinities to each enzyme form. The sites to which these inhibitors bind appear
