Reactions of Dysprosium with Adenine Nucleotides

Journal of Inorganic Biochemistry, 1988
Dysprosium 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.

Adenine nucleotides of the stria vascularis

Archives of Oto-Rhino-Laryngology, 1979
The 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

Blood adenine nucleotides in Down's syndrome

Blut Zeitschrift für die Gesamte Blutforschung, 1971
The levels of ATP, ADP and AMP were estimated in the blood of children with trisomic Down's syndrome. A 19% decrease of the three adenine nucleotides per unit packed-cell volume was found. The significance of these data with respect to the macrocytosis found in patients with Down's syndrome is discussed.

Adenine Nucleotide Metabolism of Human Platelets

Thrombosis and Haemostasis, 1971
SummaryAfter platelet-rich plasma was incubated with radioactive adenine, radioactive adenine nucleotides in platelets were separated by two-dimensional thin-layer chromatography.Radioactive adenine was selectively incorporated into adenine nucleotides.

Effect of adenine nucleotides on reactions involving triphosphopyridine nucleotide

Biochimica et Biophysica Acta, 1955
Oxidized TPN, and P-ADPR have been found to be competitive inhibitors of the TPNH-cytochrome c reductase of horse liver. 2′ AMP also competitively inhibits, at somewhat higher concentrations. DPN, ADPR, desamino TPN, 3′ AMP, 5′ AMP, 2′ IMP, and 3′ IMP produce very slight or no inhibition.

Adenine nucleotides in thrombocytes of birds

Cell Biochemistry and Function, 1984
AbstractAnalysis 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.

Extracellular Adenine Nucleotide Catabolism in Heart Valves

Nucleosides, Nucleotides and Nucleic Acids, 2014
Enzymes of extracellular nucleotide catabolism, such as ecto-nucleoside triphosphate diphosphohydrolase (eNTPD), ecto-5'-nucleotidase (e5NT) and ecto-adenosine deaminase (eADA), control extracellular concentrations of adenine nucleotides and adenosine, furthermore in that way regulate inflammation, immune response, and platelets aggregation. In valves,

Strong adenine clustering in nucleotide sequences

Journal of Theoretical Biology, 1980
Abstract We analyze the known long natural nucleotide sequences, looking for possible homonucleotide clustering. We find strong evidence for adenine clustering starting at the A3 level. Single, isolated As and to a lesser extent AAs occur less frequently than expected from the base composition of the given sequence alone.

Measurement of Adenine Nucleotides

1975
Classically the autonomic nervous system consists of two components, adrenergic and cholinergic nerves. There have been a number of reports of a third nerve component in the autonomic nervous system which is neither adrenergic nor cholinergic and evidence has been presented that the transmitter released from these nerves, at least in the ...

Adenine nucleotides in the carotid body

Cell and Tissue Research, 1980
Remarkably large amounts of adenine nucleotides are identified in type L-cells of the carotid body by fluorescence microscopy (labelling with quinacrine) and electron microscopy (uranaffin reaction). At the fine-structural level of the matrix material of specific granules displays enhanced electron density after fixation with uranium ions.
