Membrane recognition and dynamics of the RNA degradosome. [PDF]
RNase E, which is the central component of the multienzyme RNA degradosome, serves as a scaffold for interaction with other enzymes involved in mRNA degradation including the DEAD-box RNA helicase RhlB.

The social fabric of the RNA degradosome. [PDF]
Bacterial transcripts each have a characteristic half-life, suggesting that the processes of RNA degradation work in an active and selective manner. Moreover, the processes are well controlled, thereby ensuring that degradation is orderly and coordinated.

The RNase J-Based RNA Degradosome Is Compartmentalized in the Gastric Pathogen
Posttranscriptional regulation is a major level of gene expression control in any cell. In bacteria, multiprotein machines called RNA degradosomes are central for RNA processing and degradation, and some were reported to be compartmentalized inside these

Attachment of the RNA degradosome to the bacterial inner cytoplasmic membrane prevents wasteful degradation of rRNA in ribosome assembly intermediates. [PDF]
RNA processing and degradation shape the transcriptome by generating stable molecules that are necessary for translation (rRNA and tRNA) and by facilitating the turnover of mRNA, which is necessary for the posttranscriptional control of gene expression ...

Multi-scale ensemble properties of the Escherichia coli RNA degradosome. [PDF]
AbstractIn organisms from all domains of life, multi‐enzyme assemblies play central roles in defining transcript lifetimes and facilitating RNA‐mediated regulation of gene expression. An assembly dedicated to such roles, known as the RNA degradosome, is found amongst bacteria from highly diverse lineages.

Localization of components of the RNA-degrading machine in Bacillus subtilis [PDF]
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 ...

Cooperation of regulatory RNA and the RNA degradosome in transcript surveillance. [PDF]
Abstract The ompD transcript, encoding an outer membrane porin in Salmonella, harbors a controlling element in its coding region that base-pairs imperfectly with a ‘seed’ region of the small regulatory RNA (sRNA) MicC. When tagged with the sRNA, the ompD mRNA is cleaved downstream of the pairing site by the conserved endoribonuclease ...

Dimeric assembly of human Suv3 helicase promotes its RNA unwinding function in mitochondrial RNA degradosome for RNA decay. [PDF]
AbstractHuman Suv3 is a unique homodimeric helicase that constitutes the major component of the mitochondrial degradosome to work cooperatively with exoribonuclease PNPase for efficient RNA decay. However, the molecular mechanism of how Suv3 is assembled into a homodimer to unwind RNA remains elusive.

Structural analysis of mtEXO mitochondrial RNA degradosome reveals tight coupling of nuclease and helicase components [PDF]
The mitochondrial RNA degradosome (mtEXO) plays an essential role in the regulation of mitochondrial gene expression and is composed of the 3′-to-5′ exoribonuclease Dss1 and the helicase Suv3.

Structural elucidation of a novel mechanism for the bacteriophage-based inhibition of the RNA degradosome [PDF]
In all domains of life, the catalysed degradation of RNA facilitates rapid adaptation to changing environmental conditions, while destruction of foreign RNA is an important mechanism to prevent host infection.
