SR7 – a dual-function antisense RNA from Bacillus subtilis

RNA Biology, 2021
Here, we describe SR7, a dual-function antisense RNA encoded on the Bacillus subtilis chromosome. This RNA was earlier described as SigB-dependent regulatory RNA S1136 and reported to reduce the amount of the small ribosomal subunit under ethanol stress.

Synthesis of empty bacterial microcompartments, directed organelle protein incorporation, and evidence of filament-associated organelle movement [PDF]

, 2010
Compartmentalization is an important process, since it allows the segregation of metabolic activities and, in the era of synthetic biology, represents an important tool by which defined microenvironments can be created for specific metabolic functions ...

The Sole DEAD-Box RNA Helicase of the Gastric Pathogen Helicobacter pylori Is Essential for Colonization

mBio, 2018
Present in every kingdom of life, generally in multiple copies, DEAD-box RNA helicases are specialized enzymes that unwind RNA secondary structures. They play major roles in mRNA decay, ribosome biogenesis, and adaptation to cold temperatures.

Maturation of Polycistronic mRNAs by the Endoribonuclease RNase Y and Its Associated Y-Complex in Bacillus Subtilis [PDF]

, 2018
Endonucleolytic cleavage within polycistronic mRNAs can lead to differential stability, and thus discordant abundance, among cotranscribed genes. RNase Y, the major endonuclease for mRNA decay in Bacillus subtilis, was originally identified for its ...

Studies of the RNA Degradosome-organizing Domain of the Escherichia coli Ribonuclease RNase E [PDF]

Journal of Molecular Biology, 2004
The hydrolytic endoribonuclease RNase E, which is widely distributed in bacteria and plants, plays key roles in mRNA degradation and RNA processing in Escherichia coli. The enzymatic activity of RNase E is contained within the conserved amino-terminal half of the 118 kDa protein, and the carboxy-terminal half organizes the RNA degradosome, a multi ...

Adenovirus type 5 E4 Orf3 protein targets promyelocytic leukaemia (PML) protein nuclear domains for disruption via a sequence in PML isoform II that is predicted as a protein interaction site by bioinformatic analysis [PDF]

, 2009
Human adenovirus type 5 infection causes the disruption of structures in the cell nucleus termed promyelocytic leukaemia (PML) protein nuclear domains or ND10, which contain the PML protein as a critical component. This disruption is achieved through the

A Mitochondria-Specific Isoform of FASTK Is Present In Mitochondrial RNA Granules and Regulates Gene Expression and Function

Cell Reports, 2015
The mitochondrial genome relies heavily on post-transcriptional events for its proper expression, and misregulation of this process can cause mitochondrial genetic diseases in humans.

Controlling the mitochondrial antisense – role of the SUV3-PNPase complex and its co-factor GRSF1 in mitochondrial RNA surveillance

Molecular & Cellular Oncology, 2018
Transcription of the human mitochondrial genome produces a vast amount of non-coding antisense RNAs. These RNA species can form G-quadraplexes (G4), which affect their decay. We found that the mitochondrial degradosome, a complex of RNA helicase SUPV3L1 (
