Incorporation of Adenosine and Adenosine Triphosphate into Rat Myocardium

Computerized modeling of adenosine triphosphate, adenosine triarsenate and adenosine trivanadate.

Computerized molecular models of adenosine triphosphate, adenosine tri-arsenate and adenosine trivanadate have been generated using the molecular mechanics technique. The analysis of structural parameters indicated that, at least theoretically, adenosine triarsenate is a realistic candidate for replacement of adenosine triphosphate in biochemical pathways. On the contrary, the structural arrang...

Adenosine 59-Triphosphate: a P2-Purinergic Agonist in the Myocardium

Adenosine triphosphate inhibition in myosin adenosine triphosphate systems.

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 nucleoside triphosphatase activity of myosin A could be qual...
