The advantage of channeling nucleotides for very processive functions [version 1; referees: 3 approved]

open access: yesF1000Research, 2017
Nucleoside triphosphate (NTP)s, like ATP (adenosine 5’-triphosphate) and GTP (guanosine 5’-triphosphate), have long been considered sufficiently concentrated and diffusible to fuel all cellular ATPases (adenosine triphosphatases) and GTPases (guanosine ...

ATP8B2-Mediated Asymmetric Distribution of Plasmalogens Regulates Plasmalogen Homeostasis and Plays a Role in Intracellular Signaling

open access: yesFrontiers in Molecular Biosciences, 2022
Plasmalogens are a subclass of glycerophospholipid containing vinyl-ether bond at the sn-1 position of glycerol backbone. Ethanolamine-containing plasmalogens (plasmalogens) are major constituents of cellular membranes in mammalian cells and de novo ...

The effect of triethyltin on oxidative phosphorylation and mitochondrial adenosine triphosphatase activation [PDF]

open access: yes, 1961
Triethyltin inhibits the respiration of rat brain slices following in vitro and in vivo administration. When added in vitro this alkyltin compound uncouples oxidative phosphorylation of rat brain and liver homogenates and mitochondria.

The effect of calcium to magnesium ratio on adenosine triphosphatases from wheat roots

open access: yesActa Societatis Botanicorum Poloniae, 2015
The activities of ATPase isolated from 4 days old wheat roots grown on distilled water were found to be associated with the ratio of Ca : Mg ions added in different proportions to the incubation medium. This relationship was stated in the crude cell wall

AAA+ ATPases in Protein Degradation: Structures, Functions and Mechanisms

open access: yesBiomolecules, 2020
Adenosine triphosphatases (ATPases) associated with a variety of cellular activities (AAA+), the hexameric ring-shaped motor complexes located in all ATP-driven proteolytic machines, are involved in many cellular processes.

Activity-dependent release of Adenosine: a critical re-evaluation of mechanism [PDF]

open access: yes, 2008
Adenosine is perhaps the most important and universal modulator in the brain. The current consensus is that it is primarily produced in the extracellular space from the breakdown of previously released ATP.

Adenosine-mediated modulation of ventral horn interneurons and spinal motoneurons in neonatal mice [PDF]

open access: yes, 2015
The authors are grateful for support from the Wellcome Trust.Neuromodulation allows neural networks to adapt to varying environmental and biomechanical demands. Purinergic signalling is known to be an important modulatory system in many parts of the CNS,

SUB-CHRONIC COMBINED TOXIC EFFECT OF ETHEPHON AND GIBBERELLIC ACID ON MICE BRAIN MITOCHONDRIAL ADENOSINE TRI-PHOSPHATASES AND BOTH BRAIN AND WHOLE BLOOD ACETYLCHOLINEESTERASE [PDF]

open access: yesJournal of Animal and Poultry Production, 2010
The objective of the present study was to assess the sub-chronic effect of combination between ethephon and gibberellic acid on brain mitochondrial adenosine tri-phosphatas, brain and whole blood acetyl cholinesterase.

Galangin ameliorates changes of membrane–bound enzymes in rats with streptozotocin–induced hyperglycemia

open access: yesAsian Pacific Journal of Tropical Biomedicine, 2019
Objective: To assess the protective effect of galangin on membrane bound enzymes in rats with streptozotocin-induced diabetes. Methods: A single low dose of streptozotocin was injected to adult male albino rats to induce hyperglycemia. Galangin (8 mg/kg)

Activity-dependent adenosine release may be linked to activation of Na+-K+ ATPase : an in vitro rat study [PDF]

open access: yes, 2014
In the brain, extracellular adenosine increases as a result of neuronal activity. The mechanisms by which this occurs are only incompletely understood. Here we investigate the hypothesis that the Na+ influxes associated with neuronal signalling activate ...
