Current perspectives of the Escherichia coli RNA degradosome

Biotechnology Letters, 2011
Many biological processes in the cell are linked to RNA metabolism and therefore have implications for a wide range of biotechnological applications. The processing and degradation of RNA plays an important role in RNA metabolism with often the same enzymes being involved in both processes.

Dynamics of the canonical RNA degradosome components during glucose stress

Biochimie, 2021
The RNA Degradosome (RNAD) is a multi-enzyme complex, which performs important functions in post-transcriptional regulation in Escherichia coli with the assistance of regulatory sRNAs and the RNA chaperone Hfq. Although the interaction of the canonical RNAD components with RNase E has been extensively studied, the dynamic nature of the interactions in ...

Recognition of Enolase in the Escherichia coli RNA Degradosome

Journal of Molecular Biology, 2006
In Escherichia coli, the glycolytic enzyme enolase is a component of the RNA degradosome, which is an RNase E mediated assembly involved in RNA processing and transcript turnover. The recruitment of enolase by the RNA degradosome has been implicated in the turnover of certain transcripts, and it is mediated by a small segment of roughly a dozen ...

The assembly and distribution in vivo of the Escherichia coli RNA degradosome

Biochimie, 2013
We report an analysis in vivo of the RNA degradosome assembly of Escherichia coli. Employing fluorescence microscopy imaging and fluorescence energy transfer (FRET) measurements, we present evidence for in vivo pairwise interactions between RNase E-PNPase (polynucleotide phosphorylase), and RNase E-Enolase.

Escherichia coli RNA Degradosome

2001
Publisher Summary The Escherichia coli RNA degradosome is a nucleolytic complex containing four integral components: ribonuclease E (RNase E), polynucleotide phosphorylase (PNPase), RNA helicase B (RhlB), and enolase. This complex was discovered during efforts to purify and characterize RNase E, which is a singlestrand-specific endoribonuclease ...

Analysis of the Escherichia coli RNA degradosome composition by a proteomic approach

Biochimie, 2006
The RNA degradosome is a bacterial protein machine devoted to RNA degradation and processing. In Escherichia coli it is typically composed of the endoribonuclease RNase E, which also serves as a scaffold for the other components, the exoribonuclease PNPase, the RNA helicase RhlB, and enolase.

A DEAD-box RNA helicase in the Escherichia coli RNA degradosome

Nature, 1996
The Escherichia coli RNA degradosome is a multi-enzyme complex that contains the exoribonuclease polynucleotide phosphorylase (PNPase) and the endoribonuclease RNase E. Both enzymes are important in RNA processing and messenger RNA degradation. Here we report that enolase and RhlB are two other major components of the degradosome.

Analysis of the RNA degradosome complex in Vibrio angustum S14

The FEBS Journal, 2010
The RNA degradosome is built on the C‐terminal half of ribonuclease E (RNase E) which shows high sequence variation, even amongst closely related species. This is intriguing given its central role in RNA processing and mRNA decay. Previously, we have identified RhlB (ATP‐dependent DEAD‐box RNA helicase)‐binding, PNPase (polynucleotide phosphorylase ...
