Adenine Nucleotide and Nicotinamide Adenine Dinucleotide Measurements in Plants [PDF]

Current Protocols in Plant Biology, 2020
AbstractAs the principal co‐factors of many metabolic pathways, the measurement of both adenine nucleotides and nicotinamide adenine dinucleotide provides important information about cellular energy metabolism. However, given their rapid and reversible conversion as well as their relatively low concentration ranges, it is difficult to measure these ...

Relevance of πσ* states in the photoinduced processes of adenine, adenine dimer, and adenine–water complexes

The Journal of Chemical Physics, 2005
Ab initio calculations and time-resolved photoionization spectroscopy were carried out to characterize the role of the lowest two πσ* excited states for the photoinduced processes in the adenine monomer, adenine dimer, and adenine–water clusters. The calculations show—with respect to the monomer—a stabilization of 0.11–0.14 eV for the πσ* states in ...

Quadracyclic Adenine: A Non‐Perturbing Fluorescent Adenine Analogue

Chemistry – A European Journal, 2012
AbstractFluorescent‐base analogues (FBAs) comprise a group of increasingly important molecules for the investigation of nucleic acid structure and dynamics as well as of interactions between nucleic acids and other molecules. Here, we report on the synthesis, detailed spectroscopic characterisation and base‐pairing properties of a new environment ...

Preorganized Internal Electric Field Promotes a Double-displacement Mechanism for the Adenine Excision Reaction by Adenine DNA Glycosylase [PDF]

, 2023
Adenine DNA glycosylase (MutY) is a monofunctional glycosylase, removing adenines (A) misinserted opposite 8-oxo-7,8-dihydroguanine (OG), a common product of oxidative damage to DNA.

Tautomerisation Mechanisms in the Adenine-Thymine Nucleobase Pair During DNA Strand Separation [PDF]

, 2022
The adenine-thymine tautomer (A*-T*) has previously been discounted as a spontaneous mutagenesis mechanism due to the energetic instability of the tautomeric configuration.

Nanoporous Cu(II)-Adenine-Based Metal–Organic Frameworks for Selective Adsorption of C₂H₂ from C₂H₄ and CO₂

, 2023
In some important chemical processes, selective removal of C2H2 from other gases is necessary. The method of selecting porous materials for separation is energy-efficient and economical in comparison with some traditional methods, such as solvent ...

Uraemic Cardiomyopathy in Different Mouse Models

Frontiers in Medicine, 2021
Uraemic cardiomyopathy (UCM) is one of the most common complications in chronic kidney disease (CKD). Our aim was to compare characteristics of various UCM mouse models. Mice were assigned to the following groups: the pole ligation group, 5/6 nephrectomy

Metal-ion binding and metal-ion induced folding of the adenine-sensing riboswitch aptamer domain [PDF]

, 2010
Divalent cations are important in the folding and stabilization of complex RNA structures. The adenine-sensing riboswitch controls the expression of mRNAs for proteins involved in purine metabolism by directly sensing intracellular adenine levels ...

Comparative analysis of inflammatory and oxidative stress indicators in rat models of CKD induced by adenine versus folic acid; an experimental study [PDF]

Journal of Nephropathology
Introduction: Chronic kidney disease (CKD) is a progressive condition characterized by inflammation, oxidative stress, and significant renal dysfunction. Animal models are indispensable for studying CKD pathophysiology and testing therapeutic strategies.
