Crystal structure of the Escherichia coli RNA degradosome component enolase [PDF]

open access: yesJournal of Molecular Biology, 2001
The crystal structure of Escherichia coli enolase (EC 4.2.1.11, phosphopyruvate hydratase), which is a component of the RNA degradosome, has been determined at 2.5 A. There are four molecules in the asymmetric unit of the C2 cell, and in one of the molecules, flexible loops close onto the active site.

Unraveling new roles for minor components of the E. coli RNA degradosome [PDF]

open access: hybridRNA Biology, 2009
Endoribonuclease E, 3'-5' exoribonuclease polynucleotide phosphorylase, RhlB RNA helicase and enolase form a multienzyme complex (the "degradosome") playing an important role in RNA processing and decay in Escherichia coli. Although a number of proteins that occasionally co-purify with the E.

Distinct co-evolution patterns of genes associated to DNA polymerase III DnaE and PolC

open access: yesBMC Genomics, 2012
Background Bacterial genomes displaying a strong bias between the leading and the lagging strand of DNA replication encode two DNA polymerases III, DnaE and PolC, rather than a single one.

The exoribonuclease Polynucleotide Phosphorylase influences the virulence and stress responses of yersiniae and many other pathogens

open access: yesFrontiers in Cellular and Infection Microbiology, 2013
Microbes are incessantly challenged by both biotic and abiotic stressors threatening their existence. Therefore, bacterial pathogens must possess mechanisms to successfully subvert host immune defenses as well as overcome the stress associated with host ...

LEVELNET to visualize, explore, and compare protein–protein interaction networks

open access: yesPROTEOMICS, Volume 23, Issue 17, September 2023., 2023
Abstract Physical interactions between proteins are central to all biological processes. Yet, the current knowledge of who interacts with whom in the cell and in what manner relies on partial, noisy, and highly heterogeneous data. Thus, there is a need for methods comprehensively describing and organizing such data.

Caught in the act—Visualizing ribonucleases during eukaryotic ribosome assembly

open access: yesWIREs RNA, Volume 14, Issue 4, July/August 2023., 2023
Ribonucleolytic processing of precursor ribosomal RNAs is an essential aspect of ribosome production. Structural snapshots of pre‐ribosomal particles provide new insights into how ribonuclease activities are regulated spatially and temporally during ribosome assembly.

RNA components of Escherichia coli degradosome: Evidence for rRNA decay [PDF]

open access: yesProceedings of the National Academy of Sciences, 1998
Recently, we found that a multicomponent ribonucleolytic degradosome complex formed around RNase E, a key mRNA-degrading and 9S RNA-processing enzyme, contains RNA in addition to its protein components. Herein we show that the RNA found in the degradosome consists primarily of rRNA fragments that have a range of distinctive sizes.

Localization of components of the RNA-degrading machine in Bacillus subtilis

open access: yesFrontiers in Microbiology, 2016
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 ...

Structural insights into RNase J that plays an essential role in Mycobacterium tuberculosis RNA metabolism

open access: yesNature Communications, 2023
Ribonucleases (RNases) are responsible for RNA metabolism. RNase J, the core enzyme of the RNA degradosome, plays an essential role in global mRNA decay.

Allosteric activation of RhlB by RNase E induces partial duplex opening in substrate RNA

open access: yesFrontiers in Molecular Biosciences, 2023
The E. coli DEAD-Box helicase RhlB is responsible for ATP-dependent unwinding of structured mRNA to facilitate RNA degradation by the protein complex degradosome.
