Mechanisms and Pathological Significance of Liquid–Liquid Phase Separation in Bacteria

open access: yesThe FASEB Journal, Volume 39, Issue 18, 30 September 2025.
LLPS in bacterial infections. In biological systems, the molecular mechanisms underlying LLPS are primarily driven by multivalent protein–protein interactions, protein‐nucleic acid interactions, and intramolecular interactions mediated by IDR. Through LLPS, proteins form condensates that function as ‘microfactories,’ playing crucial roles in regulating

Hfq and Hfq-dependent small RNAs are major contributors to multicellular development inSalmonella entericaserovar Typhimurium [PDF]

open access: yesRNA Biology, 2012
The RNA chaperone Hfq and its associated small RNAs (sRNAs) regulate a variety of phenotypes in bacteria. In this work, we show that Hfq is a master regulator of biofilm formation in Salmonella enterica serovar Typhimurium. Hfq and two Hfq-dependent sRNAs (ArcZ and SdsR) are required for rdar morphotype expression in S. typhimurium.

Interconnection of post-transcriptional regulation: The RNA-binding protein Hfq is a novel target of the Lon protease in Pseudomonas aeruginosa [PDF]

open access: yes, 2015
Besides being a major opportunistic human pathogen, Pseudomonas aeruginosa can be found in a wide range of environments. This versatility is linked to complex regulation, which is achieved through the action of transcriptional regulators, and post ...

Adaptive Tolerance of Listeria monocytogenes to Chemical Oxidants: Comparative Analysis of Transcriptomic Studies

open access: yesComprehensive Reviews in Food Science and Food Safety, Volume 24, Issue 5, September 2025.
ABSTRACT Listeria monocytogenes is a foodborne pathogen that poses significant challenges to food safety and public health due to its ability to adapt to harsh environments, particularly those found in food processing facilities. This review explores the global transcriptional responses of L.

The RNA Chaperone Hfq Is Involved in Colony Morphology, Nutrient Utilization and Oxidative and Envelope Stress Response in Vibrio alginolyticus. [PDF]

open access: yesPLoS ONE, 2016
Hfq is a global regulator that is involved in environmental adaptation of bacteria and in pathogenicity. To gain insight into the role of Hfq in Vibrio alginolyticus, an hfq deletion mutant was constructed in V.

Acinetobacter baumannii as a Model for the Study and Application of Gram‐Negative Outer Membrane Vesicles: A Systematic Review

open access: yesMicrobial Biotechnology, Volume 18, Issue 9, September 2025.
Investigation of outer membrane vesicles from Acinetobacter baumannii for potential biotechnological applications. ABSTRACT Outer membrane vesicles (OMVs) are extracellular nanostructures released from Gram‐negative bacteria. Acinetobacter baumannii OMVs (AbOMVs) have been extensively studied and can thus be used as a model for understanding multiple ...

Functional Characterization of a Global Virulence Regulator Hfq and Identification of Hfq-Dependent sRNAs in the Plant Pathogen Pantoea ananatis

open access: yesFrontiers in Microbiology, 2019
To successfully infect plant hosts, the collective regulation of virulence factors in a bacterial pathogen is crucial. Hfq is an RNA chaperone protein that facilitates the small RNA (sRNA) regulation of global gene expression at the post-transcriptional ...

Archaeal protein containing domain of unknown function 2193 undergoes oligomeric reconfiguration upon iron–sulfur cluster binding

open access: yesFEBS Letters, Volume 599, Issue 16, Page 2318-2333, August 2025.
This work presents the characterization of MvoDUF2193, a Methanococcus voltae (Mvo) protein from the domain of unknown function (DUF) 2193 family. We demonstrate that MvoDUF2193 binds a single [4Fe–4S] cluster per subunit and that cluster occupancy regulates the transition from an apo tetramer to a [4Fe–4S] monomeric form. This structural transition is

Deletion of the small RNA chaperone protein Hfq down regulates genes related to virulence and confers protection against wild-type Brucella challenge in mice

open access: yesFrontiers in Microbiology, 2016
Brucellosis is one of the most common zoonotic epidemics worldwide. Brucella, the etiological pathogen of brucellosis, has unique virulence characteristics, including the ability to survive within the host cell.

Phage‐mediated horizontal transfer of Salmonella enterica virulence genes with regulatory feedback from the host

open access: yesiMeta, Volume 4, Issue 4, August 2025.
In this study, we found evidence of phage‐mediated horizontal transfer of virulence genes in Salmonella enterica in global habitats from a molecular evolutionary perspective. Notably, csrA, a global regulator in Salmonella enterica, curbed horizontal gene transfer by inhibiting the cyclization and release of prophage.
