Adenosine Triphosphate Inhibition in Myosin Adenosine Triphosphate Systems
Abstract Factors affecting inhibition of myosin ATPase by ATP, such as concentration of the enzyme, of ATP, and of the divalent metals, calcium and magnesium, have been studied and the results are reported here. Experiments were carried out under conditions in which no known magnesium effects occurred, so that only the effect of calcium on the ...

Imaging Adenosine Triphosphate (ATP) [PDF]
Adenosine triphosphate (ATP) is a universal mediator of metabolism and signaling across unicellular and multicellular species. There is a fundamental interdependence between the dynamics of ATP and the physiology that occurs inside and outside the cell.

Adenosine Triphosphate in Milk
Freshly secreted goat's milk contains a number of viable metabolic pathways including those for the synthesis of triglycerides and phospholipids. Toward understanding this matter, amounts of the fundamentally important energy substrate, adenosine triphosphate, in goat's milk were evaluated.

Adenosine triphosphate stimulates Aquifex aeolicus MutL endonuclease activity. [PDF]
BACKGROUND:Human PMS2 (hPMS2) homologues act to nick 5' and 3' to misincorporated nucleotides during mismatch repair in organisms that lack MutH. Mn(++) was previously found to stimulate the endonuclease activity of these homologues. ATP was required for

NMR of $^{31}$P Nuclear Spin Singlet States in Organic Diphosphates [PDF]
$^{31}$P NMR and MRI are commonly used to study organophosphates that are central to cellular energy metabolism. In some molecules of interest, such as adenosine diphosphate (ADP) and nicotinamide adenine dinucleotide (NAD), pairs of coupled $^{31}$P nuclei in the diphosphate moiety should enable the creation of nuclear spin singlet states, which may ...

ABC gene expression profiles have clinical importance and possibly form a new hallmark of cancer
Adenosine triphosphate–binding cassette proteins constitute a large family of active transporters through extracellular and intracellular membranes. Increased drug efflux based on adenosine triphosphate–binding cassette protein activity is related to the

Application of the adenosine triphosphate sensitivity assay in infantile vascular anomalies
Background The term vascular anomalies include various vascular tumors and vascular malformations, among them infantile hemangiomas and capillary malformations are the most well-known associated diseases in early ages. Multiple drugs have been introduced

New Algorithm of Stress Echocardiography with Adenosine Triphosphate
Objective. Submaximal myocardial hyperemia is known not to be achieved in 16-18% of cases during cardiac stress tests and monotonic intracubital administration of adenosine triphosphate (ATP) at a dose of 140-160 pg/kg/min.

Adenosine Triphosphate in Mammalian Spermatozoa [PDF]
THE presence of adenosine triphosphoric acid (that is, of readily hydrolysable phosphorus) in mammalian spermatozoa has been established by Ivanov and Kanygina1 and by Lardy, Hansen and Phillips2.
