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 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 Eq+librium Constants of the Adenosine Triphosphate Hydrolysis and the Adenosine Triphosphate- Citrate Lyase Reactions
The observed standard free energy change (AGibs) for the hydrolysis of the terminal pyrophosphate bond of ATP has been experimentally determined under physiological conditions using an entirely new set of reactions. The observed equilibrium constant (K,,bs) for the combined reactions of acetate kinase (EC 2.7.2.1) and phosphate acetyltransferase (EC 2.3.1.8) has been determined at 38”, pH 7.0, ...

متن کاملInhibition by Adenosine 5'-Triphosphate
Two major species of glucose-6-phosphate dehydrogenase (EC 1.1.1.49) differing in size, pyridine nucleotide specificity, and susceptibility to inhibition by adenosine 5'-triphosphate (ATP) were detected in extracts of Pseudomonas multivorans (which has recently been shown to be synonymous with the species Pseudomonas cepacia) ATCC 17616. The large species (molecular weight ca. 230,000) was acti...
