The RNA processing enzyme polynucleotide phosphorylase negatively controls biofilm formation by repressing poly-N-acetylglucosamine (PNAG) production in Escherichia coli C

BMC Microbiology, 2012
Background Transition from planktonic cells to biofilm is mediated by production of adhesion factors, such as extracellular polysaccharides (EPS), and modulated by complex regulatory networks that, in addition to controlling production of adhesion ...

Rat liver mitochondrial polynucleotide phosphorylase

FEBS Letters, 1971
We have recently isolated, partially purified and demonstrated the specificity of a polynucleotide phosphorylase from crude guinea-pig liver nuclei [ 1,2] The enzyme was associated with membrane lipids and catalysed the phosphorolysis of polyribonucleotides to ribonucleoside diphosphates.

Regulatory Mechanisms of Exoribonuclease PNPase and Regulatory Small RNA on T3SS of Dickeya dadantii

Molecular Plant-Microbe Interactions, 2010
The type III secretion system (T3SS) is an essential virulence factor for many bacterial pathogens. Polynucleotide phosphorylase (PNPase) is one of the major exoribonucleases in bacteria and plays important roles in mRNA degradation, tRNA processing, and

Strategies for Detecting Aminoacylation and Aminoacyl‐tRNA Editing in vitro and in Cells

Israel Journal of Chemistry, Volume 64, Issue 8-9, September 2024.
Abstract Aminoacyl‐tRNA synthetases (aaRSs) maintain translational fidelity by ensuring the formation of correct aminoacyl‐tRNA pairs. Numerous point mutations in human aaRSs have been linked to disease phenotypes. Structural studies of aaRSs from human pathogens encoding unique domains support these enzymes as potential candidates for therapeutics ...

Arabidopsis chloroplast quantitative editotype [PDF]

, 2013
Chloroplast C-to-U RNA editing is an essential post-transcriptional process. Here we analyzed RNA editing in Arabidopsis thaliana using strand-specific deep sequencing datasets from the wild-type and a mutant defective in RNA 3′ end maturation.

The number of domains in the ribosomal protein S1 as a hallmark of the phylogenetic grouping of bacteria.

PLoS ONE, 2019
The family of ribosomal proteins S1 contains about 20% of all bacterial proteins including the S1 domain. An important feature of this family is multiple copies of structural domains in bacteria, the number of which changes in a strictly limited range ...
