Pseudouridines and Pseudouridine Synthases of the Ribosome

open access: yesCold Spring Harbor Symposia on Quantitative Biology, 2001
psi are ubiquitous in ribosomal RNA. Eubacteria, Archaea, and eukaryotes all contain psi, although their number varies widely, with eukaryotes having the most. The small ribosomal subunit can apparently do without psi in some organisms, even though others have as many as 40 or more.

Variance in translational fidelity of different bacterial species is affected by pseudouridines in the tRNA anticodon stem-loop

open access: yesRNA Biology, 2022
Delicate variances in the translational machinery affect how efficiently different organisms approach protein synthesis. Determining the scale of this effect, however, requires knowledge on the differences of mistranslation levels.

Unveiling the role of PUS7-mediated pseudouridylation in host protein interactions specific for the SARS-CoV-2 RNA genome

open access: yesMolecular Therapy: Nucleic Acids, 2023
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a positive single-stranded RNA virus, engages in complex interactions with host cell proteins throughout its life cycle. While these interactions enable the host to recognize and inhibit viral

Dynamic regulation and key roles of ribonucleic acid methylation

open access: yesFrontiers in Cellular Neuroscience, 2022
Ribonucleic acid (RNA) methylation is the most abundant modification in biological systems, accounting for 60% of all RNA modifications, and affects multiple aspects of RNA (including mRNAs, tRNAs, rRNAs, microRNAs, and long non-coding RNAs ...

Ribosomal RNA pseudouridines and pseudouridine synthases [PDF]

open access: yesFEBS Letters, 2002
Pseudouridines are found in virtually all ribosomal RNAs but their function is unknown. There are four to eight times more pseudouridines in eukaryotes than in eubacteria. Mapping 19 Haloarcula marismortui pseudouridines on the three‐dimensional 50S subunit does not show clustering.

Pseudouridine Synthases

open access: yesChemistry & Biology, 2006
Pseudouridine synthases are the enzymes responsible for the most abundant posttranscriptional modification of cellular RNAs. These enzymes catalyze the site-specific isomerization of uridine residues that are already part of an RNA chain, and appear to employ both sequence and structural information to achieve site specificity.

The Critical Contribution of Pseudouridine to mRNA COVID-19 Vaccines

open access: yesFrontiers in Cell and Developmental Biology, 2021
The current COVID-19 pandemic is a massive source of global disruption, having led so far to two hundred and fifty million COVID-19 cases and almost five million deaths worldwide.

tRNA Modifications: Impact on Structure and Thermal Adaptation

open access: yesBiomolecules, 2017
Transfer RNAs (tRNAs) are central players in translation, functioning as adapter molecules between the informational level of nucleic acids and the functional level of proteins.

The regulation of antiviral innate immunity through non-m6A RNA modifications

open access: yesFrontiers in Immunology, 2023
The post-transcriptional RNA modifications impact the dynamic regulation of gene expression in diverse biological and physiological processes. Host RNA modifications play an indispensable role in regulating innate immune responses against virus infection

Chemistry of Fluorinated Pyrimidines in the Era of Personalized Medicine

open access: yesMolecules, 2020
We review developments in fluorine chemistry contributing to the more precise use of fluorinated pyrimidines (FPs) to treat cancer. 5-Fluorouracil (5-FU) is the most widely used FP and is used to treat > 2 million cancer patients each year.
