Deuterated nucleotides as chemical probes of RNA structure: a detailed protocol for the enzymatic synthesis of a complete set of nucleotides specifically deuterated at ribose carbons [PDF]
, 2015 We describe here a detailed protocol for the synthesis of ribonucleotides specifically deuterated at each ribose carbon atom. We synthesized 20 specifically deuterated ribonucleotides: ATP, CTP, GTP, and UTP, each of which contained one of five ...

ATP as a presynaptic modulator [PDF]
, 2000 © 2000 Elsevier Science Inc.There is considerable evidence that ATP acts as a fast transmitter or co-transmitter in autonomic and sensory nerves mostly through activation of ionotropic P2X receptors but also through metabotropic P2Y receptors. By analogy,

Journal of Neuroscience, 1997 There are multiple mechanisms by which adenine nucleotides can be released into the extracellular space in brain. Adenine nucleotides are converted extracellularly to adenosine, which then acts on adenosine receptors to elicit physiological responses ...

Pathways of adenine nucleotide catabolism in erythrocytes. [PDF]
Journal of Clinical Investigation, 1986 The exact pathway whereby the initial catabolism of the adenine nucleotides proceeds from AMP and the possibility of a recycling of adenosine were investigated in human erythrocytes. Adenine nucleotide catabolism, reflected by the production of hypoxanthine, is very slow under physiologic conditions and can be greatly increased by suppression of ...

The hypoxic tissue microenvironment as a driver of mucosal inflammatory resolution
Frontiers in Immunology, 2023 On the backdrop of all acute inflammatory processes lies the activation of the resolution response. Recent years have witnessed an emerging interest in defining molecular factors that influence the resolution of inflammation.

Modelling the ATP production in mitochondria [PDF]
Bulletin Math. Biology 75, 1636 (2013), 2012 We revisit here the mathematical model for ATP production in mitochondria introduced recently by Bertram, Pedersen, Luciani, and Sherman (BPLS) as a simplification of the more complete but intricate Magnus and Keizer's model. We identify some inaccuracies in the BPLS original approximations for two flux rates, namely the adenine nucleotide translocator

Dependence of nucleotide physical properties on their placement in codons and determinative degree
, 2007 Various physical properties such as dipole moment, heat of formation and energy of the most stable formation of nucleotides and bases were calculated by PM3 (modified neglect of diatomic overlap, parametric method number 3) and AM1 (Austin model 1 ...

Increased Adenine Nucleotide Degradation in Skeletal Muscle Atrophy [PDF]
, 2019 Adenine nucleotides (AdNs: ATP, ADP, AMP) are essential biological compounds that facilitate many necessary cellular processes by providing chemical energy, mediating intracellular signaling, and regulating protein metabolism and solubilization.
