Journal of Fish Diseases, EarlyView.ABSTRACT Outbreaks of vibriosis caused by Vibrio anguillarum are a persistent constraint on rainbow trout (Oncorhynchus mykiss) aquaculture. However, information on the population structure of field strains in Turkey has been lacking. Here, we report the first systematic serotypic, proteomic, and genomic characterization of 23 V.

Regulation of fixLJ by Hfq Controls Symbiotically Important Genes in Sinorhizobium meliloti
Molecular Plant-Microbe Interactions, 2016 The RNA-binding chaperone Hfq plays critical roles in the establishment and functionality of the symbiosis between Sinorhizobium meliloti and its legume hosts. A mutation in hfq reduces symbiotic efficiency resulting in a Fix− phenotype, characterized by

RNAs Associated With Bacterial Outer Membrane Vesicles: Structural Insights Into Surface Composition
Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.This work uncovers a new layer of bacterial communication. We show that RNAs, aided by the Hfq RNA‐chaperone, are not only packed inside Gram negative Outer Membrane Vesicles (OMVs) but can also be embedded in their membranes. This suggests that bacteria may use surface‐exposed RNAs to directly interact with host cells. Overall, our results broaden the

Role of the Sinorhizobium meliloti Global Regulator Hfq in Gene Regulation and Symbiosis
Molecular Plant-Microbe Interactions, 2010 The RNA-binding protein Hfq is a global regulator which controls diverse cellular processes in bacteria. To begin understanding the role of Hfq in the Sinorhizobium meliloti–Medicago truncatula nitrogen-fixing symbiosis, we defined free-living and ...

Identifying Subcellular Structure Components in Escherichia Coli by Crosslinking and SEC‐MS
PROTEOMICS, Volume 26, Issue 5, Page 27-36, May 2026.ABSTRACT Cells are comprised of a broad spectrum of structures that compartmentalize biochemical and signaling mechanisms. These structures can be comprised of many biomolecules, but especially lipids, proteins, and nucleic acids. Techniques are limited to quantify or discover new subcellular structures.

Hfq stimulates the activity of the CCA-adding enzyme [PDF]
BMC Molecular Biology, 2007 Abstract Background The bacterial Sm-like protein Hfq is known as an important regulator involved in many reactions of RNA metabolism. A prominent function of Hfq is the stimulation of RNA polyadenylation catalyzed by E. coli poly(A) polymerase I (PAP).

Non-Coding RNA, 2021 Many RNA-RNA interactions depend on molecular chaperones to form and remain stable in living cells. A prime example is the RNA chaperone Hfq, which is a critical effector involved in regulatory interactions between small RNAs (sRNAs) and cognate target ...

Journal of Extracellular Biology, Volume 5, Issue 4, April 2026.ABSTRACT Klebsiella pneumoniae (K. pneumoniae) has become a global threat due to the convergence of carbapenem resistance and hypervirulence. Outer membrane vesicles (OMVs) play important roles in bacterial pathogenicity, yet their functional coordination with strains remains unclear.
