Nucleotides: Structure and Properties [PDF]

open access: yes, 2005
Nucleotides consist of a nitrogen-containing base, a five-carbon sugar, and one or more phosphate groups. Cells contain many types of nucleotides, which play a central role in a wide variety of cellular processes, including metabolic regulation and the ...

Genetic predisposition to porto‐sinusoidal vascular disorder: A functional genomic‐based, multigenerational family study

open access: yesHepatology, EarlyView., 2022
A deleterious variant of FCHSD1 results in mTOR pathway overactivation and may cause porto‐sinusoidal vascular disorder (PSVD). The pedigree of the family demonstrated an autosomal dominant disease with variable expressivity. Whole‐genome sequencing and Sanger sequencing both validated the existence of the FCHSD1 variant and the heterozygosity of c ...

Interplay Between Capsule Expression and Uracil Metabolism in Streptococcus pneumoniae D39

open access: yesFrontiers in Microbiology, 2018
Pyrimidine nucleotides play an important role in the biosynthesis of activated nucleotide sugars (NDP-sugars). NDP-sugars are the precursors of structural polysaccharides in bacteria, including capsule, which is a major virulence factor of the human ...

Nonsynonymous Mutations in Linker-2 of the Pdr5 Multidrug Transporter Identify a New RNA Stability Element

open access: yesG3: Genes, Genomes, Genetics, 2020
Analysis of synonymous mutations established that although the primary amino acid sequence remains unchanged, alterations in transcription and translation can result in significant phenotypic consequences. We report the novel observation that a series of

Expression of microRNAs in Horse Plasma and Their Characteristic Nucleotide Composition. [PDF]

open access: yesPLoS ONE, 2016
MicroRNAs (miRNAs) in blood plasma are stable under high levels of ribonuclease activity and could function in tissue-to-tissue communication, suggesting that they may have distinctive structural characteristics compared with non-circulating miRNAs.

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]

open access: yes, 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 ...

Raman depolarization ratios in RNA and DNA are sensitive for sugar-base coupling [PDF]

open access: yes, 1995
Polarized and depolarized Raman spectra are obtained for a number of synthetic polynucleotides containing adenine, uracil, and thymine bases. The depolarization ratios are determined by two methods: (1) by dividing the -spectrum by the -spectrum and (2 ...

Three-dimensional modeling of single stranded DNA hairpins for aptamer-based biosensors. [PDF]

open access: yes, 2017
Aptamers consist of short oligonucleotides that bind specific targets. They provide advantages over antibodies, including robustness, low cost, and reusability.

Turning On Uracil-DNA Glycosylase Using a Pyrene Nucleotide Switch [PDF]

open access: yesJournal of Biological Chemistry, 2001
Base flipping is a highly conserved process by which enzymes swivel an entire nucleotide from the DNA base stack into their active site pockets. Uracil DNA glycosylase (UDG) is a paradigm enzyme that uses a base flipping mechanism to catalyze the hydrolysis of the N-glycosidic bond of 2'-deoxyuridine (2'-dUrd) in DNA as the first step in uracil base ...
