The formation of thymidine triphosphate in cell-free extracts of Escherichia coli was reported in 1957 to require deoxyuridylate, formaldehyde, dZ,n-tetrahydrofolate, Mg++, and adenosine triphosphate (1). It soon became apparent through use of chromatographic procedures that ATP was not involved in the primary conversion of deoxyuridylate to thymidylate, and that the over-all reaction could be ...

Background Imatinib mesylate, a small-molecular analog of adenosine triphosphate (ATP) that potently inhibits tyrosine kinase activities of Bcr–Abl, PDGFR-β, PDGFR-α, c-Fms, Arg and c-kit, is one of the novel molecularly targeted drugs being introduced into cancer therapy. We tested the effect of imatinib on the ovarian histological structure and the concentration of estrogen and progesterone, ...

Abstract Background In this paper, a simple, enzyme-free, label-free fluorescence, high sensitivity logic gate hairpin aptasensor was developed for adenosine triphosphate (ATP) detection based on graphene oxide (GO) and PicoGreen dye. Methods Using single-strand deoxyribonucleic acid (DNA) as input signal fluorescence output signal, if DNA (DNA-L), (DNA-S), ATP were present at the same time, on...

Using the DNA recombination technique, a new bacterial strain Escherichia coli DAC-22 was derived, whose cells are able to carry out heterologous expression of Bacillus thuringiensis diadenylate cyclase – enzyme catalyzing reaction adenosine-5′-triphosphate (ATP) transformation into cyclic 3′,5′-diadenylate (cyclo-di-AMP). To derive strain, E. “Rosetta (DE3) pLysS” were originally used as recip...

Net synthesis of adenosine 5'-triphosphate (ATP) in energy-depleted cells of Escherichia coli was observed when an inwardly directed protonmotive force was artificially imposed. In wild-type cells, ATP synthesis occurred whether the protonmotive force was dominated by the membrane potential (negative inside) or the pH gradient (alkaline inside). Formation of ATP did not occur unless the protonm...

Actions of adenosine triphosphate (ATP) on neurons of the substantia gelatinosa (SG) were evaluated in spinal cord slices using tight-seal, whole-cell recordings. Bath-applied ATP activated a fast inward current and potentiated both glutamate-induced and synaptically evoked currents by acting through a purinergic receptor with the pharmacology of the P2 type. ATP also induced a delayed slow out...

ATP and ADP activate functionally distinct G protein-coupled purinergic (P2Y) receptors. We determined the expression and function of adenine nucleotide-specific P2Y receptors on cord blood-derived human mast cells (hMCs). Human MCs expressed mRNA encoding the ADP-specific P2Y1, P2Y12, and P2Y13 receptors; the ATP/UTP-specific P2Y2 receptor; and the ATP-selective P2Y11 receptor. ADP (0.05-50 mu...

This study examines the effects of metabolic inhibitors on the content of cellular K, Na, and adenosine triphosphate (ATP). ATP and K are seen to fall in the inhibited tissues. The ATP content is correlated with the K content. The role of ATP is examined according to a recent biophysical approach. It is suggested that ATP may control the electrolyte levels by inducing conformational changes in ...

Adenosine 5'-triphosphate (ATP) is released from the cytoplasm under physiologic and pathophysiologic conditions and enters the extracellular space, where it acts on a group of recently cloned cell-surface receptors termed P2-purinoceptors (subtypes P2X and P2Y). We examined the effects of extracellular ATP, uridine triphosphate (UTP), the stable ATP analogues alpha,betamethylene-ATP (alpha,bet...
