Insight into an Oxidative DNA-Cleaving DNAzyme: Multiple Cofactors, the Catalytic Core Map and a Highly Efficient Variant

iScience, 2020
Summary: An oxidative DNA-cleaving DNAzyme (PL) employs a double-cofactor model “X/Cu2+” for catalysis. Herein, we verified that reduced nicotinamide adenine dinucleotide (NADH), flavin mononucleotide, cysteine, dithiothreitol, catechol, resorcinol ...

Substrate binding in the mitochondrial ADP/ATP carrier is a step-wise process guiding the structural changes in the transport cycle

Nature Communications, 2022
The mitochondrial ADP/ATP carrier transports adenine nucleotides. Here, authors identify the residues involved in substrate binding. One set forms the central substrate binding site and two asparagine/arginine pairs help to guide the substrates during ...

The evolution of purinergic receptors involved in recognition of a blood meal by hematophagous insects

Memorias do Instituto Oswaldo Cruz, 1987
Many blood feeders use adenine nucleotides as cues for locating blood meal. Structure-activity relationship of adenine nucleotides as phagostimulants varies between closely-related species of blood feeders. It is suggested that a preexisting diverse pool

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 ...

Development and application of LC/HRPS for quantification of adenine nucleotides, creatine phosphate, and creatine in sturgeon spermatozoa

Czech Journal of Animal Science, 2017
The objective of this study was to investigate the applicability of liquid chromatography coupled with high resolution product scan (LC/HRPS) mass spectrometry for simultaneous quantification of adenine nucleotides, creatine phosphate, and creatine ...

Conformationally Restricted Adenine Nucleotide Analogs in Mitochondrial Adenine Nucleotide Transport

Zeitschrift für Naturforschung C, 1978
Abstract The conformationally restricted adenine nucleotide analogs 8,3′anhydro-8-oxy-9-(β-ᴅ-xylofurano-syl) adenine-5′-O-tri (di) -phosphate (I) , and 8,2′-anhydro-8-oxy-9-(β-ᴅ-arabinofuranosyl) adenine-5′-O-tri (di)-phosphate (II), were prepared chemically as their α- 32 P-

Phylogenetic analysis of Anguilla marmorata population in Thua Thien Hue, Vietnam based on the cytochrome C oxidase I (COI) gene fragments

AMB Express, 2020
The giant mottled eel is a species with high commercial value so overfishing, river management, and water pollution have negatively affected its movement and population numbers. Anguilla marmorata (eel) was listed in the Vietnam Red Data Book 2007 with a

Control of ATP homeostasis during the respiro‐fermentative transition in yeast

Molecular Systems Biology, 2010
Respiring Saccharomyces cerevisiae cells respond to a sudden increase in glucose concentration by a pronounced drop of their adenine nucleotide content ([ATP]+[ADP]+[AMP]=[AXP]).

RNA Capping by Transcription Initiation with Non-canonical Initiating Nucleotides (NCINs): Determination of Relative Efficiencies of Transcription Initiation with NCINs and NTPs

Bio-Protocol, 2017
It recently has been established that adenine-containing cofactors, including nicotinamide adenine dinucleotide (NAD+), reduced nicotinamide adenine dinucleotide (NADH), and 3’-desphospho-coenzyme A (dpCoA), can serve as ‘non-canonical initiating ...

Evaluation of functioning of mitochondrial electron transport chain with NADH and FAD autofluorescence [PDF]

The Ukrainian Biochemical Journal, 2016
We prove the feasibility of evaluation of mitochondrial electron transport chain function in isolated mitochondria of smooth muscle cells of rats from uterus using fluorescence of NADH and FAD coenzymes. We found the inversely directed changes in FAD and
