Comprehensive 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.

E. coli DNA associated with isolated Hfq interacts with Hfq's distal surface and C-terminal domain [PDF]
Biochimica et Biophysica Acta (BBA) - Gene Regulatory Mechanisms, 2010 The RNA-binding protein Hfq has been studied extensively for its function as a modulator of gene expression at the post-transcriptional level. While most Hfq studies have focused on the protein's interaction with sRNAs and mRNAs, Hfq binding to DNA has been observed but is less explored.

Structural and biochemical studies on ATP binding and hydrolysis by the Escherichia coli RNA chaperone Hfq. [PDF]
PLoS ONE, 2012 In Escherichia coli the RNA chaperone Hfq is involved in riboregulation by assisting base-pairing between small regulatory RNAs (sRNAs) and mRNA targets. Several structural and biochemical studies revealed RNA binding sites on either surface of the donut

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 ...

Microbial 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 ...

FEBS 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

Sm‐like protein Hfq: Location of the ATP‐binding site and the effect of ATP on Hfq–RNA complexes [PDF]
Protein Science, 2007 AbstractSm‐like proteins are ubiquitous ring‐shaped oligomers that exhibit a variety of nucleic acid‐binding activities. They have been linked functionally to various cellular events involving RNA, and it is generally believed that their activity is exerted via the passive binding of nucleic acids.

iMeta, 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.

Hfq affects mRNA levels independently of degradation [PDF]
BMC Molecular Biology, 2010 Abstract Background The bacterial Lsm protein, Hfq, is an RNA chaperone involved in many reactions related to RNA metabolism, such as replication and stability, control of small RNA activity and polyadenylation. Despite this wide spectrum of known functions, the global role of Hfq is almost certainly undervalued; its ...

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