Interplay between bacterial 5′-NAD-RNA decapping hydrolase NudC and DEAD-box RNA helicase CsdA in stress responses

mSystems, 2023
Both prokaryotic and eukaryotic RNAs can be 5′-capped by the metabolite nicotinamide adenine dinucleotide (NAD). Nudix hydrolases, such as bacterial NudC, specifically remove NAD-caps; however, the molecular and cellular functions of these ...

Biophysical characterization of the Escherichia coli RNA degradosome

, 2022
In Escherichia coli, post-transcriptional regulation is a tightly controlled process facilitated by a multi-enzyme complex, the RNA degradosome. The core components of the RNA degradosome consist of the endoribonuclease RNase E, the DEAD-box helicase RhlB, the glycolytic enzyme enolase, and the exoribonuclease PNPase. The main scaffold component of the

Structural analysis of mtEXO mitochondrial RNA degradosome reveals tight coupling of nuclease and helicase components

Nature Communications, 2018
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.

Ribonuclease E organizes the protein interactions in the Escherichia coli RNA degradosome [PDF]

Genes & Development, 1998
The Escherichia coli RNA degradosome is the prototype of a recently discovered family of multiprotein machines involved in the processing and degradation of RNA. The interactions between the various protein components of the RNA degradosome were investigated by Far Western blotting, the yeast two-hybrid assay, and coimmunopurification experiments.

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.

Reconstitution and Analysis of the Multienzyme Escherichia coli RNA Degradosome

Journal of Molecular Biology, 2008
The Escherichia coli RNA degradosome is a multienzyme assembly that functions in transcript turnover and maturation of structured RNA precursors. We have developed a procedure to reconstitute the RNA degradosome from recombinant components using modular coexpression vectors.

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 (

The RNA processing enzyme polynucleotide phosphorylase negatively controls biofilm formation by repressing poly-N-acetylglucosamine (PNAG) production in Escherichia coli C

BMC Microbiology, 2012
Background Transition from planktonic cells to biofilm is mediated by production of adhesion factors, such as extracellular polysaccharides (EPS), and modulated by complex regulatory networks that, in addition to controlling production of adhesion ...

Formation of a stable RNase Y-RicT (YaaT) complex requires RicA (YmcA) and RicF (YlbF)

mBio, 2023
In Bacillus subtilis, the RicT (YaaT), RicA (YmcA), and RicF (YlbF) proteins, which form a stable ternary complex, are needed together with RNase Y (Rny) to cleave and thereby stabilize several key transcripts encoding enzymes of intermediary metabolism.
