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

open access: yesAMB 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

open access: yesMolecular 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

open access: yesBio-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]

open access: yesThe 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

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

open access: yes, 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 ...

Water-mediated recognition of t1-adenosine anchors Argonaute2 to microRNA targets

open access: yeseLife, 2015
MicroRNAs (miRNAs) direct post-transcriptional regulation of human genes by guiding Argonaute proteins to complementary sites in messenger RNAs (mRNAs) targeted for repression.

Adenine nucleotides in mammalian platelets and avian thrombocytes [PDF]

open access: yes, 1988
In avian thtorabocytes, like in mammalian blood plateleta the adenine nucleotides are present in three distinguishable compartments. For studies of adenine nucleotide metabolic pool the turkey thrombocytes were prelabeled with 3 H-adenine.

CapZyme-Seq: A 5′-RNA-Seq Method for Differential Detection and Quantitation of NAD-Capped and Uncapped 5′-Triphosphate RNA

open access: yesSTAR Protocols, 2020
Summary: Nucleoside-containing metabolites such as the oxidized and reduced forms of nicotinamide adenine dinucleotide (NAD+ and NADH), 3′-desphospho-coenzyme A (dpCoA), and flavin adenine dinucleotide (FAD) can be incorporated as RNA 5′ end caps by ...

Substrate Nucleotide-Determined Non-Templated Addition of Adenine by Taq DNA Polymerase: Implications for PCR-Based Genotyping and Cloning

open access: yesBioTechniques, 1996
The Applied Biosystems PRISMTM fluorescence-based genotyping system as well as the Invitrogen TA Cloning® vector system are influenced by the tendency of Taq DNA polymerase to add an adenine nucleotide to the 3′ end of PCR products after extension ...

Structural Basis of SARS-CoV-2 Polymerase Inhibition by Favipiravir

open access: yesThe Innovation, 2021
Summary: The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has developed into an unprecedented global pandemic. Nucleoside analogs, such as Remdesivir and Favipiravir, can serve as the first-line broad-spectrum antiviral drugs ...
