Substrate specificity of the pseudouridine synthase RluD in Escherichia coli [PDF]
Pseudouridine synthase RluD converts uridines at positions 1911, 1915, and 1917 of 23S rRNA to pseudouridines. These nucleotides are located in the functionally important helix‐loop 69 of 23S rRNA. RluD is the only pseudouridine synthase that is required for normal growth in Escherichia coli.

Novel variants in PUS7 associated with intellectual disability and growth retardation: expanding the clinical spectrum in 13 patients. ABSTRACT Pseudouridylation is a frequent post‐transcriptional modification resulting in uridine isomerization in 5‐ribosyluracil, also called pseudouridine. This mechanism leads to RNA stability with an increase in base‐

Implications of RNA pseudouridylation for cancer biology and therapeutics: a narrative review
Background Pseudouridine (Ψ), a C5-glycoside isomer of uridine, stands as one of the most prevalent RNA modifications in all RNA types. Distinguishing from the C-N bond linking uridine to ribose, the link between Ψ and ribose is a C-C bond, endowing Ψ ...

The WHO Classification of Genetic Tumour Syndromes: Considerations for Genetics
The WHO Classification of Tumours underpins the diagnosis of neoplastic conditions. The new WHO classification of genetic tumour syndromes (GTS) provides international standards for their diagnosis. This diagram highlights the chromosomal distribution of the genes involved in the GTS covered in this classification.

The Crystal Structure of E. coli rRNA Pseudouridine Synthase RluE [PDF]
Pseudouridine synthase RluE modifies U2457 in a stem of 23 S RNA in Escherichia coli. This modification is located in the peptidyl transferase center of the ribosome. We determined the crystal structures of the C-terminal, catalytic domain of E. coli RluE at 1.2 A resolution and of full-length RluE at 1.6 A resolution.

Comparative study of two box H/ACA ribonucleoprotein pseudouridine-synthases: relation between conformational dynamics of the guide RNA, enzyme assembly and activity. [PDF]
Multiple RNA-guided pseudouridine synthases, H/ACA ribonucleoprotein particles (RNPs) which contain a guide RNA and four proteins, catalyze site-specific post-transcriptional isomerization of uridines into pseudouridines in substrate RNAs.

ABSTRACT Celiac disease (CeD) is an autoimmune enteropathy triggered by gluten ingestion in genetically predisposed individuals, who frequently present HLA‐DQ2 or HLA‐DQ8 haplotypes. To examine the genetic architecture of CeD in the admixed South Brazilian population, we sequenced the HLA alleles to high resolution and genotyped 16 non‐HLA ...

RluD is the pseudouridine synthase responsible for the formation of Ψ1911, Ψ1915, and Ψ1917 in Escherichia coli 23S rRNA. Previous work from our laboratory demonstrated that disruption of the rluD gene and/or loss of the pseudouridine residues for which ...

Dual Inhibition of DKC1 and MEK1/2 Synergistically Restrains the Growth of Colorectal Cancer Cells
Colorectal cancer, one of the most commonly diagnosed cancers worldwide, is often accompanied by uncontrolled proliferation of tumor cells. Dyskerin pseudouridine synthase 1 (DKC1), screened using the genome‐wide RNAi strategy, is a previously ...

GK PUA Domain Modulates Cables, Cooperativity, and Proline Feedback
EcGK tetramers hierarchically assemble into metabolic filaments and bundle into metabolic cables. Upon substrate binding, this dynamic equilibrium shifts from inactive cables to active tetramers to drive catalysis; meanwhile the inhibitor proline stabilizes an X‐shaped conformation, redirecting assembly toward filaments to enable efficient feedback ...
