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

Toxin-mediated ribosome stalling reprograms the Mycobacterium tuberculosis proteome

open access: yesNature Communications, 2019
MazF endoribonucleases are thought to arrest growth of Mycobacterium tuberculosis by global translation inhibition. Here, Barth et al. show that MazF-mt9 cleaves a specific tRNA, leading to ribosome stalling at AAA codons and thus selective mRNA ...

Regulation of RNase E during the UV stress response in the cyanobacterium Synechocystis sp. PCC 6803

open access: yesmLife, 2023
Endoribonucleases govern the maturation and degradation of RNA and are indispensable in the posttranscriptional regulation of gene expression. A key endoribonuclease in Gram‐negative bacteria is RNase E.

Role of Dicer-Dependent RNA Interference in Regulating Mycoparasitic Interactions

open access: yesMicrobiology Spectrum, 2021
Dicer-like proteins (DCLs) play a vital role in RNA interference (RNAi), by cleaving RNA filament into small RNAs. Although DCL-mediated RNAi can regulate interspecific communication between pathogenic/mutualistic organisms and their hosts, its role in ...

The Continuing Story of Endoribonuclease III

open access: yesMicrobial Physiology, 2004
Endoribonuclease III (RNase III) plays an important role in the processing of rRNA and mRNAs. It is timely to summarize the most relevant insights obtained during the last years stemming from RNase III. With this aim, the present mini-review provides a wealth of new information focusing on the distribution and architecture of RNase III, substrate ...

Novel specificity of an endoribonuclease of yeast [PDF]

open access: yesFEBS Letters, 1986
Investigations of the cleavage specificity of a cyclizing endoribonuclease of yeast show that it hydrolyzes Y‐A bonds of single‐stranded regions of RNA and that oligonucleotides are hydrolyzed poorly. The stringent specificity of the enzyme suggests that it may be useful for generating specific fragments of polyribonucleotides.

Substrate specificity of bacterial endoribonuclease toxins

open access: yesBMB Reports, 2020
Bacterial endoribonuclease toxins belong to a protein family that inhibits bacterial growth by degrading mRNA or rRNA sequences. The toxin genes are organized in pairs with its cognate antitoxins in the chromosome and thus the activities of the toxins are antagonized by antitoxin proteins or RNAs during active translation.

Reversible and irreversible inhibitors of coronavirus Nsp15 endoribonuclease

open access: yesJournal of Biological Chemistry, 2023
The emergence of severe acute respiratory syndrome coronavirus 2, the causative agent of coronavirus disease 2019, has resulted in the largest pandemic in recent history. Current therapeutic strategies to mitigate this disease have focused on the development of vaccines and on drugs that inhibit the viral 3CL protease or RNA-dependent RNA polymerase ...

Global regulatory functions of the Staphylococcus aureus endoribonuclease III in gene expression. [PDF]

open access: yesPLoS Genetics, 2012
RNA turnover plays an important role in both virulence and adaptation to stress in the Gram-positive human pathogen Staphylococcus aureus. However, the molecular players and mechanisms involved in these processes are poorly understood.

Global analyses of small interfering RNAs derived from Bamboo mosaic virus and its associated satellite RNAs in different plants. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Satellite RNAs (satRNAs), virus parasites, are exclusively associated with plant virus infection and have attracted much interest over the last 3 decades.
