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...
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 کاملAdenosine Triphosphate-dependent Taurocholate
Transport systems involved in uptake and biliary secretion of bile salts have been extensively studied in rat liver; however, little is known about these systems in the human liver. In this study, we investigated taurocholate (TC) transport in canalicular and basolateral plasma membrane vesicles isolated from 15 human livers (donor age 6-64 yr). ATP stimulated the uptake ofTC into both canalicu...
متن کاملSynthesis of adenosine triphosphate and exchange between inorganic phosphate and adenosine triphosphate in sodium and potassium ion transport adenosine triphosphatase.
Radioactive adenosine triphosphate was synthesized transiently from adenosine diphosphate and radioactive inorganic phosphate by sodium and potassium adenosine triphosphatase from guinea pig kidney. In a first step, K+-sensitive phosphoenzyme was formed from radioactive inorganic phosphate in the presence of magnesium ion and 16 mM sodium ion. In a second step the addition to the phosphoenzyme ...
متن کاملThe adenosine triphosphate-adenosine diphosphate exchange reaction of oxidative phosphorylation.
Previous reports from this laboratory have demonstrated that the ATP-Pi32 1 exchange reaction (1) and the dinitrophenolstimulated ATPase activity (2) of mitochondrial subfragments (3-9) are reflections of intermediate enzymatic steps in the complex sequence of reactions (1, 3) in which phosphorylation of ADP is coupled to electron transport in the respiratory chain. This communication concerns ...
