Condensation properties of stress granules and processing bodies are compromised in myotonic dystrophy type 1

open access: yesDisease Models & Mechanisms, 2022
RNA regulation in mammalian cells requires complex physical compartmentalisation, using structures thought to be formed by liquid-liquid phase separation. Disruption of these structures is implicated in numerous degenerative diseases.

A mutant of uracil DNA glycosylase that distinguishes between cytosine and 5-methylcytosine [PDF]

open access: yes, 2014
We demonstrate that a mutant of uracil DNA glycosylase (N123D:L191A) distinguishes between cytosine and methylcytosine. Uracil DNA glycosylase (UDG) efficiently removes uracil from DNA in a reaction in which the base is flipped into the enzyme’s active ...

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 ...

Involvement of uracil nucleotides in protection of cardiomyocytes from hypoxic stress [PDF]

open access: yesBiochemical Pharmacology, 2005
Cardiomyocytes express one or more subtypes of P2 receptors for extracellular nucleotides. P2 purinoceptors, which are activated by nucleotides, are classified as P2X or P2Y: P2X receptors are ligand-gated intrinsic ion channels, and P2Y receptors are G protein-coupled receptors.

Architecturally diverse proteins converge on an analogous mechanism to inactivate Uracil-DNA glycosylase [PDF]

open access: yes, 2013
Uracil-DNA glycosylase (UDG) compromises the replication strategies of diverse viruses from unrelated lineages. Virally encoded proteins therefore exist to limit, inhibit or target UDG activity for proteolysis.

Short Term Effect of Caffeine on Purine, Pyrimidine and Pyridine Metabolism in Rice () Seedlings

open access: yesNatural Product Communications, 2015
As part of our studies on the physiological and ecological function of caffeine, we investigated the effect of exogenously supplied caffeine on purine, pyrimidine and pyridine metabolism in rice seedlings.

Effects of different temperatures and diets on nutritional and bio‐functional components in the juvenile lined seahorse (Hippocampus erectus)

open access: yesJournal of the World Aquaculture Society, 2023
A two‐factorial experiment (temperature with three levels: 23°C, 25.5°C and 28°C; diet with four kinds: live Artemia sp., copepods, live Artemia sp. + copepods and frozen Neomysis awatschensis [FNA]) was carried out to evaluate the effects of different ...

Structure Characterization of Escherichia coli Pseudouridine Kinase PsuK

open access: yesFrontiers in Microbiology, 2022
Pseudouridine (Ψ) is one of the most abundant RNA modifications in cellular RNAs that post-transcriptionally impact many aspects of RNA. However, the metabolic fate of modified RNA nucleotides has long been a question. A pseudouridine kinase (PsuK) and a

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

Crystal structure and functional implications of cyclic di-pyrimidine-synthesizing cGAS/DncV-like nucleotidyltransferases

open access: yesNature Communications, 2023
Purine-containing nucleotide second messengers regulate diverse cellular activities. Cyclic di-pyrimidines mediate anti-phage functions in bacteria; however, the synthesis mechanism remains elusive.
