mRNA structure determines modification by pseudouridine synthase 1. [PDF]

open access: yesNat Chem Biol, 2019
Pseudouridine (Ψ) is a post-transcriptional RNA modification that alters RNA-RNA and RNA-protein interactions that affect gene expression. Messenger RNA pseudouridylation was recently discovered as a widespread and conserved phenomenon, but the mechanisms responsible for selective, regulated pseudouridylation of specific sequences within mRNAs were ...

An investigation into eukaryotic pseudouridine synthases [PDF]

open access: yesJournal of Bioinformatics and Computational Biology, 2014
A common post-transcriptional modification of RNA is the conversion of uridine to its isomer pseudouridine. We investigated the biological significance of eukaryotic pseudouridine synthases using the yeast Saccharomyces cerevisiae. We conducted a comprehensive statistical analysis on growth data from automated perturbation (gene deletion) experiments,

Cloning and characterization of a mammalian pseudouridine synthase [PDF]

open access: yesRNA, 1999
This report describes the cloning and characterization of a pseudouridine (psi) synthase from mouse that we have named mouse pseudouridine synthase 1 (mpus1p). The cDNA is approximately 1.5 kb and when used as a probe on a Northern blot of mouse RNA from tissues and cultured cells, several bands were detected.

Critical Aspartic Acid Residues in Pseudouridine Synthases [PDF]

open access: yesJournal of Biological Chemistry, 1999
The pseudouridine synthases catalyze the isomerization of uridine to pseudouridine at particular positions in certain RNA molecules. Genomic data base searches and sequence alignments using the first four identified pseudouridine synthases led Koonin (Koonin, E. V. (1996) Nucleic Acids Res.

Characterization of the Pseudouridine Synthase TruD Family [PDF]

open access: yes, 2013
RNA contains over 100 post-transcriptional chemical modifications. Of these, the most abundant is pseudouridine (Ψ), the 5’ ribosyl isomer of uridine. The formation of Ψ occurs at the polynucleotide level, and is catalyzed by Ψ synthase enzymes.

The Role of Cysteine Residues in the Rearrangement of Uridine to Pseudouridine Catalyzed by Pseudouridine Synthase I [PDF]

open access: yesJournal of Biological Chemistry, 1997
Escherichia coli tRNA pseudouridine synthase I (PSUI) catalyzes the conversion of uridine residues to pseudouridine in positions 38, 39, and 40 of various tRNA molecules. In previous biochemical studies with this enzyme (Kammen, H. O., Marvel, C. C., Hardy, L., and Penhoet, E. E. (1988) J. Biol. Chem.

Epitranscriptomics of SARS-CoV-2 Infection

open access: yesFrontiers in Cell and Developmental Biology, 2022
Recent studies on the epitranscriptomic code of SARS-CoV-2 infection have discovered various RNA modifications, such as N6-methyladenosine (m6A), pseudouridine (Ψ), and 2′-O-methylation (Nm).

Integrative multiomics evaluation reveals the importance of pseudouridine synthases in hepatocellular carcinoma

open access: yesFrontiers in Genetics, 2022
Background: The pseudouridine synthases (PUSs) have been reported to be associated with cancers. However, their involvement in hepatocellular carcinoma (HCC) has not been well documented.

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.
