Electron Transfer Precedes ATP Hydrolysis during Nitrogenase Catalysis [PDF]

open access: yes, 2013
The biological reduction of N2 to NH3 catalyzed by Mo-dependent nitrogenase requires at least eight rounds of a complex cycle of events associated with ATP-driven electron transfer (ET) from the Fe protein to the catalytic MoFe protein, with each ET ...

Effects of stunning methods on pre rigor changes in rainbow trout (Oncorhynchus mykiss) reared at two different temperatures

open access: yesItalian Journal of Animal Science, 2020
The effects of two stunning methods (carbon monoxide asphyxia, CO, and electroshock, E) on blood plasma parameters, rigor index, fillet pH and shape changes, ATP breakdown and Adenylate Energy Charge (AEC) in muscle immediately post mortem were ...

Extracellular ATP: A Feasible Target for Cancer Therapy

open access: yesCells, 2020
Adenosine triphosphate (ATP) is one of the main biochemical components of the tumor microenvironment (TME), where it can promote tumor progression or tumor suppression depending on its concentration and on the specific ecto-nucleotidases and receptors ...

Further Characterization of Dopamine Release by Permeabilized PC 12 Cells [PDF]

open access: yes, 1987
Rat pheochromocytoma cells (PC 12) permeabilized with staphylococcal α-toxin release [3H]dopamine after addition of micromolar Ca2+. This does not require additional Mg2+-ATP (in contrast to bovine adrenal medullary chromaffin cells).

ATP

open access: yesFinans/Invest, 2023
ATP’s aktive og højt gearede investeringer har gennem de sidste 10 år leveret et afkast på godt 9% om året, det samme som en passiv ugearet global aktieinvestering. ATP’s afkast har derimod været betydeligt mere usikkert. ATP har således ikke fået tilstrækkelig kompensation for den øgede risiko.

The T790M mutation in EGFR kinase causes drug resistance by increasing the affinity for ATP

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2008
Lung cancers caused by activating mutations in the epidermal growth factor receptor (EGFR) are initially responsive to small molecule tyrosine kinase inhibitors (TKIs), but the efficacy of these agents is often limited because of the emergence of drug ...

Serine biosynthesis with one carbon catabolism represents a novel pathway for ATP generation in cells using alternative glycolysis with zero net ATP production [PDF]

open access: yes, 2011
Recent experimental evidence indicates that some cancer cells have an alternative glycolysis pathway with net zero ATP production, implying that upregulation of glycolysis in these cells may not be related to the generation of ATP.

Expression and function of ATP-dependent potassium channels in zebrafish islet β-cells [PDF]

open access: yes, 2017
ATP-sensitive potassium channels (K(ATP) channels) are critical nutrient sensors in many mammalian tissues. In the pancreas, K(ATP) channels are essential for coupling glucose metabolism to insulin secretion.

P2X1 and P2X5 subunits form the functional P2X receptor in mouse cortical astrocytes [PDF]

open access: yes, 2008
ATP plays an important role in signal transduction between neuronal and glial circuits and within glial networks. Here we describe currents activated by ATP in astrocytes acutely isolated from cortical brain slices by non-enzymatic mechanical ...

Characterization of the phosphotransacetylase-acetate kinase pathway for ATP production in Porphyromonas gingivalis

open access: yesJournal of Oral Microbiology, 2019
Acetyl phosphate (AcP) is generally produced from acetyl coenzyme A by phosphotransacetylase (Pta), and subsequent reaction with ADP, catalyzed by acetate kinase (Ack), produces ATP.
