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.

Mechanisms of inhibition of adenine phosphoribosyltransferase by adenine nucleosides and nucleotides

Canadian Journal of Biochemistry, 1970
Kinetic 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

The evolution of the adenine nucleotide translocase family

Gene, 2004
Homologous genes are grouped into families whose evolution may be different in the various organisms. For the variety of the processes and the well-known mechanism of gene gain and gene loss, which takes place in genome evolution, we deal in comparative analyses with a "one-to-many" or a "many-to-many" relationship between homologous genes going from ...

Adenine Nucleotide Translocator in Heart

Molecular Genetics and Metabolism, 2000
The adenine nucleotide translocator (ANT) spans the inner mitochondrial membrane and facilitates exchange of cytosolic ADP for ATP within the mitochondrial matrix. ANT represents the most prominent single protein component of the inner mitochondrial membrane (1).

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.

Receptors for adenosine and adenine nucleotides

General Pharmacology: The Vascular System, 1991
1. A summary is provided of current classifications of receptors for the adenine nucleosides and nucleotides. 2. The origin of the division of nucleoside (P1) and nucleotide (P2) receptors is discussed as well as the subdivisions of these into A1 and A2, determined by structure activity considerations, and P2x and P2y. 3.

The adenine nucleotide translocator and the nucleotide specificity of oxidative phosphorylation

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1970
Abstract By studying P/O ratios, proton translocation and morphology of different mitochondrial preparations, it was shown, in agreement with previous work but in disagreement with a recent report, that the nucleotide specificity of the oxidative phosphorylation resides at the level of the adenine nucleotide translocator.

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.

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 ...
