Exoribonuclease RNase R protects Antarctic Pseudomonas syringae Lz4W from DNA damage and oxidative stress. [PDF]

open access: yes, 2023
Bacterial exoribonucleases play a crucial role in RNA maturation, degradation, quality control, and turnover. In this study, we have uncovered a previously unknown role of 3-5 exoribonuclease RNase R of Pseudomonas syringae Lz4W in DNA damage and ...

Crystallographic Studies of Bacterial Exoribonucleases [PDF]

open access: yesThe Scientific World JOURNAL, 2002
INTRODUCTION. Ribonucleases (RNases) play a central role in all cellular RNA processes. These processes include mRNA degradation, and maturation and turnover of stable RNAs, which are vital for the proper functioning of all cells. E. coli has served as a model system for understanding the role of ribonucleases in RNA metabolism, and eight distinct ...

Ritonavir May Inhibit Exoribonuclease Activity of Nsp14 from the SARS-CoV-2 Virus and Potentiate the Activity of Chain Terminating Drugs [PDF]

open access: yes, 2020
SARS-CoV-2 is the causative agent for the ongoing COVID19 pandemic, and this virus belongs to the Coronaviridae family. The nsp14 protein of SARS-CoV-2 houses a 3’ to 5’ exoribonuclease activity responsible for removing mismatches that arise during ...

The Absence of E. coli Nucleoid-Associated Protein FIS at Low Temperature Leads to an Adaptation Response That Causes a Shift Towards Genome Compaction in Small Rods. [PDF]

open access: yesMol Microbiol
Unlike the wild‐type BW25113, the fis null mutant is characterized by biphasic growth at 12°C. During the first phase of growth, the absence of FIS results in the formation of filaments with dispersed nucleoids. During the acclimation phase, the FIS Null Adaptation Response is activated that leads to an increase in cell division and nucleoid ...

Real-time fluorescence detection of exoribonucleases [PDF]

open access: yesRNA, 2009
The identification of RNases or RNase effectors is a continuous challenge, particularly given the current importance of RNAs in the control of genome expression. Here, we show that a fluorogenic RNA–DNA hybrid is a powerful tool for a real-time fluorescence detection and assay of exoribonucleases (RT-FeDEx).

CATALYTIC PROPERTIES OF THE EUKARYOTIC EXOSOME [PDF]

open access: yes, 2010
The eukaryotic exosome complex is built around the backbone of a 9‑subunit ring similar to phosporolytic ribonucleases such as RNase PH and polynucleotide phosphorylase (PNPase).

Exoribonucleases as Modulators of Virulence in Pathogenic Bacteria [PDF]

open access: yesFrontiers in Cellular and Infection Microbiology, 2012
Pathogenic bacteria are responsible for severe diseases worldwide. RNA stability is a major player controlling the expression of virulence factors. Ribonucleases (RNases) are the enzymes responsible for the maturation and degradation of RNA molecules (Arraiano et al., 2010; Silva et al., 2011).
