Action of Adenosine Triphosphate on Chloroplast Structure.
Mitochondria (1, 2), chloroplasts (3), and photosynthetic bacteria (4) manifest mechanochemical changes that are coupled to energy transfer reactions in their membranes. These changes in membrane structure or membrane deformations, conveniently measured by the recording of a physical parameter, such as light scattering, are closely correlated with conditions favorable for oxidative or photophos...
متن کاملEnhancement of coronary vasodilator action of adenosine triphosphate by dipyridamole.
It has been reported that previously administered dipyridamole intensifies the coronary vasodilator action of adenosine compounds. In the present study, a combination of dipyridamole and ATP at doses that alone are ineffective was examined for its effect on the coronary sinus blood flow. In 10 anesthetized dogs, heart rate, arterial blood pressure, cardiac output, and coronary sinus blood flow ...
متن کاملStudies on Adenosine Triphosphate Transphosphorylases
The isolation of the crystalline enzymes, adenosine triphosphate-creatine transphosphorylase (1) and adenosine triphosphate-adenosine 5’-phosphate transphosphorylase (2), made possible a comparative approach to the general problem of the mechanism of action of the adenosine triphosphate transphosphorylases. The present series of papers extends earlier studies from this laboratory on these enzym...
متن کاملAdenosine 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...
متن کاملThe structure of the adenosine triphosphate of Thiobacillus thiooxidans.
The adenosine triphosphate3 of Thiobacillus thiooxidans is of special interest because LePage and Umbreit (1943b) presented evidence that it differs from the adenosine triphosphate of other organisms by having the phosphate groups attached to the 3' instead of the 5' position of adenosine. All other bacteria and higher organisms so far examined contain adenosine-5'triphosphate (5'-ATP). Since d...
