The Hfq regulon of Neisseria meningitidis
The conserved RNA‐binding protein, Hfq, has multiple regulatory roles within the prokaryotic cell, including promoting stable duplex formation between small RNAs and mRNAs, and thus hfq deletion mutants have pleiotropic phenotypes. Previous proteome and transcriptome studies of Neisseria meningitidis have generated limited insight into differential ...

Prediction of Hfq in actinobacteria [PDF]
AbstractHfq is the bacterial orthologue of the eukaryotic (L)Sm family of proteins found across all domains of life and potentially an ancient protein, but it has not been found in all phyletic lines. A careful search successfully identified a distant hfq orthologue in the cyanobacteria leaving the actinobacteria as the major phylum with no known hfq ...

Riboregulators and the role of Hfq in photosynthetic bacteria [PDF]
Anoxygenic and oxygenic bacteria directly convert solar energy into biomass using photosynthesis. The formation and composition of photosynthetic complexes has to be tightly controlled in response to environmental conditions, as exposure to sunlight can be harmful due to the generation of reactive oxygen species and the damaging effects of UV ...

Hfq mutation confers increased cephalosporin resistance in Klebsiella pneumoniae [PDF]
Klebsiella pneumoniae (K. pneumoniae), is an opportunistic pathogen raising significant public health concerns owing to its multi-drug resistance. Hfq, one of the main RNA-binding proteins, is a key post-transcriptional regulator.

Functional Characterization of Acinetobacter baumannii Lacking the RNA Chaperone Hfq
The RNA chaperone Hfq is involved in the riboregulation of diverse genes via small RNAs. Recent studies have demonstrated that Hfq contributes to the stress response and the virulence of several pathogens, and the roles of Hfq vary among bacterial ...

Models of Hfq interactions with small non-coding RNA in Gram-negative and Gram-positive bacteria
Hfq is required by many Gram-negative bacteria to chaperone the interaction between small non-coding RNA (sRNA) and mRNA to facilitate annealing. Conversely and despite the presence of Hfq in many Gram-positive bacteria, sRNAs in Gram-positive bacteria ...

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.
