No detectable effect of RNA-binding protein Hfq absence in Staphylococcus aureus

BMC Microbiology, 2007
Background The RNA-binding protein Hfq is involved in stress and virulence of several pathogens, probably due to its role as mediator in small RNA (sRNA)-mRNA interactions.

Biological and transcriptomic studies reveal hfq is required for swimming, biofilm formation and stress response in Xanthomonas axonpodis pv. citri

BMC Microbiology, 2019
Background Hfq is a widely conserved bacterial RNA-binding protein which generally mediates the global regulatory activities involv ed in physiological process and virulence.

Reduced heme levels underlie the exponential growth defect of the Shewanella oneidensis hfq mutant. [PDF]

PLoS ONE, 2014
The RNA chaperone Hfq fulfills important roles in small regulatory RNA (sRNA) function in many bacteria. Loss of Hfq in the dissimilatory metal reducing bacterium Shewanella oneidensis strain MR-1 results in slow exponential phase growth and a reduced ...

Shewanella oneidensis Hfq promotes exponential phase growth, stationary phase culture density, and cell survival

BMC Microbiology, 2013
Background Hfq is an RNA chaperone protein that has been broadly implicated in sRNA function in bacteria. Here we describe the construction and characterization of a null allele of the gene that encodes the RNA chaperone Hfq in Shewanella oneidensis ...

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

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

Identifying Subcellular Structure Components in Escherichia Coli by Crosslinking and SEC‐MS

PROTEOMICS, EarlyView.
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.

The FsrA‐Mediated Iron‐Sparing Response Regulates the Biosynthesis of the Epipeptide EPE in Bacillus subtilis

Molecular Microbiology, EarlyView.
Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.

Binding of the RNA Chaperone Hfq on Target mRNAs Promotes the Small RNA RyhB-Induced Degradation in Escherichia coli

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 ...
