Effects of Hfq on the Conformation and Compaction of DNA [PDF]
Hfq is a bacterial pleiotropic regulator that mediates several aspects of nucleic acids metabolism. The protein notably influences translation and turnover of cellular RNAs. Although most previous contributions concentrated on Hfq's interaction with RNA, its association to DNA has also been observed in vitro and in vivo.

Central role for RNase YbeY in Hfq-dependent and Hfq-independent small-RNA regulation in bacteria [PDF]
Conceptual parallels exist between bacterial and eukaryotic small-RNA (sRNA) pathways, yet relatively little is known about which protein may recognize and recruit bacterial sRNAs to interact with targets. In eukaryotes, Argonaute (AGO) proteins discharge such functions.

The Pseudomonas aeruginosa CrcZ RNA interferes with Hfq-mediated riboregulation.
The RNA chaperone Hfq regulates virulence and metabolism in the opportunistic pathogen Pseudomonas aeruginosa. During carbon catabolite repression (CCR) Hfq together with the catabolite repression control protein Crc can act as a translational repressor ...

The Pleiotropic Phenotypes Caused by an hfq Null Mutation in Vibrio harveyi
Hfq is a global regulator and can be involved in multiple cellular processes by assisting small regulatory RNAs (sRNAs) to target mRNAs. To gain insight into the virulence regulation of Hfq in Vibrio harveyi, the hfq null mutant, ∆hfq, was constructed in

Regulation of virulence in Francisella tularensis by small non-coding RNAs [PDF]
Using a cDNA cloning and sequencing approach we have shown that Francisella tularensis expresses homologues of several small RNAs (sRNAs) that are well-conserved among diverse bacteria.

The bacterial Hfq protein is a versatile modulator of RNA function and is particularly important for regulation mediated by small non-coding RNAs. Hfq is a bacterial Sm protein but bears more similarity to the eukaryotic Sm-like (Lsm) family of proteins than the prototypical Sm proteins.

The hyperfine structure of highly charged $^{238}_{92}$U ions with rotationally excited nuclei [PDF]
The hyperfine structure (hfs) of electron levels of $^{238}_{92}$U ions with the nucleus excited in the low-lying rotational $2^+$ state with an energy $E_{2^+} = 44.91$ keV is investigated.

Identification of small RNAs abundant in Burkholderia cenocepacia biofilms reveal putative regulators with a potential role in carbon and iron metabolism [PDF]
Small RNAs play a regulatory role in many central metabolic processes of bacteria, as well as in developmental processes such as biofilm formation. Small RNAs of Burkholderia cenocepacia, an opportunistic pathogenic beta-proteobacterium, are to date not ...

The Hfq chaperone helps the ribosome mature [PDF]
Ribosome biogenesis is a complex process that is facilitated by a large number of assembly factors. In this issue, Andrade et al (2018) provide evidence that a widely conserved RNA chaperone, Hfq, acts as a ribosomal assembly factor in bacteria. Hfq is known to support regulation of stress response genes by small RNAs.

The Irr and RirA proteins participate in a complex regulatory circuit and act in concert to modulate bacterioferritin expression in Ensifer meliloti 1021 [PDF]
In this work we found that the bfr gene of the rhizobial species Ensifer meliloti, encoding a bacterioferritin iron storage protein, is involved in iron homeostasis and the oxidative stress response. This gene is located downstream of and overlapping the
