Localization of components of the RNA-degrading machine in Bacillus subtilis

open access: yesFrontiers in Microbiology, 2016
In bacteria, the control of mRNA stability is crucial to allow rapid adaptation to changing conditions. In most bacteria, RNA degradation is catalyzed by the RNA degradosome, a protein complex composed of endo- and exoribonucleases, RNA helicases and ...

Moonlighting in Bacillus subtilis: The Small Proteins SR1P and SR7P Regulate the Moonlighting Activity of Glyceraldehyde 3-Phosphate Dehydrogenase A (GapA) and Enolase in RNA Degradation

open access: yesMicroorganisms, 2021
Moonlighting proteins are proteins with more than one function. During the past 25 years, they have been found to be rather widespread in bacteria. In Bacillus subtilis, moonlighting has been disclosed to occur via DNA, protein or RNA binding or protein ...

A dedicated diribonuclease resolves a key bottleneck for the terminal step of RNA degradation

open access: yeseLife, 2019
Degradation of RNA polymers, an ubiquitous process in all cells, is catalyzed by specific subsets of endo- and exoribonucleases that together recycle RNA fragments into nucleotide monophosphate.

Synthesis of 5’ end-labeled RNA

open access: yesBio-Protocol, 2012
5’ end-labeled RNA molecules are useful substrates to analyse the endo- and exonucleolytic activities of various ribonucleases. Here two protocols are given to synthesize P32 labeled RNAs with a 5’ PPP or 5’ P moiety. 5’ exoribonucleases generally do not

Nuclease Activity of the Junín Virus Nucleoprotein C-Terminal Domain

open access: yesViruses, 2023
The mammarenavirus Junín (JUNV) is the causative agent of Argentine hemorrhagic fever, a severe disease of public health concern. The most abundant viral protein is the nucleoprotein (NP), a multifunctional, two-domain protein with the primary role as ...

PNPase is involved in the coordination of mRNA degradation and expression in stationary phase cells of Escherichia coli

open access: yesBMC Genomics, 2018
Background Exoribonucleases are crucial for RNA degradation in Escherichia coli but the roles of RNase R and PNPase and their potential overlap in stationary phase are not well characterized.

RNase J1 and J2 Are Host-Encoded Factors for Plasmid Replication

open access: yesFrontiers in Microbiology, 2021
Plasmids need to ensure their transmission to both daughter-cells when their host divides, but should at the same time avoid overtaxing their hosts by directing excessive host-resources toward production of plasmid factors.

Rapid Depletion of DIS3, EXOSC10, or XRN2 Reveals the Immediate Impact of Exoribonucleolysis on Nuclear RNA Metabolism and Transcriptional Control

open access: yesCell Reports, 2019
Summary: Cell-based studies of human ribonucleases traditionally rely on methods that deplete proteins slowly. We engineered cells in which the 3′→5′ exoribonucleases of the exosome complex, DIS3 and EXOSC10, can be rapidly eliminated to assess their ...

The conserved stem-loop II structure at the 3' untranslated region of Japanese encephalitis virus genome is required for the formation of subgenomic flaviviral RNA.

open access: yesPLoS ONE, 2018
Flaviviruses accumulate abundant subgenomic RNA (sfRNA) in infected cells. It has been reported that sfRNA results from stalling of host 5'-to-3' exoribonuclease XRN1 at the highly structured RNA of the 3' untranslated region (UTR).

Biochemical Characterization of Exoribonuclease Encoded by SARS Coronavirus [PDF]

open access: yesBMB Reports, 2007
The nsp14 protein is an exoribonuclease that is encoded by severe acute respiratory syndrome coronavirus (SARS-CoV). We have cloned and expressed the nsp14 protein in Escherichia coli, and characterized the nature and the role(s) of the metal ions in the reaction chemistry.
