Enzyme-based field-effect transistor for adenosine triphosphate (ATP) sensing.
Adenosine triphosphate (ATP) not only functions as an energy-carrier substance and an informative molecule, but also acts as a marker substance in studies of both bio-traces and cellular/tissular viability. Due to the importance of the ATP function for living organisms, in situ assays of ATP are in demand in various fields, e.g., hygiene. In the present study, we developed an ATP sensor that co...
متن کاملAdenosine 5′-triphosphate (ATP) synthesis by oxidative phosphorylation or photophosphorylation
phosphorylation or photophosphorylation is a multi-step, membrane-located process that provides the bulk of cellular energy in eukaryotes and many prokaryotes. Most of the ATP synthesis in these cells is catalyzed by the enzyme, F1Fo-ATP synthase, also called F1Fo-ATPase (F-ATPase), which in its simplest, bacterial, form is composed of eight subunits (α3:β3:γ:δ:ε:a:b2:c9–12). The archaeal A1Ao-...
متن کاملAdenosine triphosphate-guided pulmonary vein isolation for atrial fibrillation: the UNmasking Dormant Electrical Reconduction by Adenosine TriPhosphate (UNDER-ATP) trial.
AIMS Most of recurrent atrial tachyarrhythmias after pulmonary vein isolation (PVI) for atrial fibrillation (AF) are due to reconnection of PVs. The aim of the present study was to evaluate whether elimination of adenosine triphosphate (ATP)-induced dormant PV conduction by additional energy applications during the first ablation procedure could reduce the incidence of recurrent atrial tachyarr...
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...
