Association of the Cold Shock DEAD-Box RNA Helicase RhlE to the RNA Degradosome in $\textit{Caulobacter crescentus}$ [PDF]
, 2017 In diverse bacterial lineages, multienzyme assemblies have evolved that are central elements of RNA metabolism and RNA-mediated regulation. The aquatic Gram-negative bacterium $\textit{Caulobacter crescentus}$, which has been a model system for studying ...

MedComm, Volume 6, Issue 9, September 2025.In quiescent PECs, Eno1 binds to the 3′ UTR of CXCL12 mRNA to prevent translation. Following activation, lactate is accumulated and then mediates an increase in lysine lactylation. Eno1, a substrate in this modification, releases bound CXCL12 mRNA upon lactylation to promote translation. Meanwhile, the activity of Eno1 as a glycolytic enzyme increases,

BMC Genomics, 2021 Background The polynucleotide phosphorylase (PNPase) is conserved among both Gram-positive and Gram-negative bacteria. As a core part of the Escherichia coli degradosome, PNPase is involved in maintaining proper RNA levels within the bacterial cell.

Phase Separation Regulates Metabolism, Mitochondria, and Diseases
MedComm, Volume 6, Issue 7, July 2025.Mitochondrion‐related liquid–liquid phase separation. (1) Phase separation mediates the self‐assembly of mitochondrial nucleoids (mt‐nucleoids). (2) Phase segregation mediates the formation of mitochondrial RNA granules (MRGs). (3) Phase separation mediates the formation of mitochondrial degradosomes.

Molecular Microbiology, Volume 123, Issue 6, Page 531-546, June 2025.Nucleoid‐associated proteins play a crucial role in the compaction of bacterial DNA and the regulation of gene expression. The emergence of small noncoding RNAs as regulatory elements in these processes represents a major development in our understanding of bacterial biology.

Polyphosphate: The “Dark Matter” of Bacterial Chromatin Structure
Molecular Microbiology, Volume 123, Issue 3, Page 279-293, March 2025.Polyphosphate condensates and their contributions to nucleoid structure. Polyphosphate condensates form in the ribosome‐depleted nucleoid region of bacterial cells, particularly under stress (in this case Pseudomonas aeruginosa undergoing nitrogen starvation; adapted with permission from (Racki et al. 2017)). This Perspective explores the emerging view

A proteomic approach to the analysis of RNA degradosome composition in Escherichia coli
, 2008 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 ...

Effects of lipid membranes on RNA catalytic activity and stability
Biology of the Cell, Volume 117, Issue 2, February 2025.This study explores how lipid membranes influence the activity and stability of natural ribozymes. We found that lipid membranes can both decrease and enhance ribozyme activity. We also observed that lipid membranes promote RNA degradation, depending on lipid composition and membrane fluidity.
