Special Focus Hfq [PDF]

open access: yesRNA Biology, 2013
In all domains of life, non-coding RNAs (ncRNAs) play a central role in cellular biology. In bacteria, the systematic discovery and analysis of ncRNAs revealed a large repertoire of regulatory transcripts, which among other characteristics is responsible for the high adaptability of prokaryotes.

The RNA chaperone Hfq is important for growth and stress tolerance in Francisella novicida.

open access: yesPLoS ONE, 2011
The RNA-binding protein Hfq is recognized as an important regulatory factor in a variety of cellular processes, including stress resistance and pathogenesis.

Apomorphine Targets the Pleiotropic Bacterial Regulator Hfq [PDF]

open access: yesAntibiotics, 2021
Hfq is a bacterial regulator with key roles in gene expression. The protein notably regulates translation efficiency and RNA decay in Gram-negative bacteria, thanks to its binding to small regulatory noncoding RNAs. This property is of primary importance for bacterial adaptation and survival in hosts.

Post-transcriptional regulator Hfq binds catalase HPII: crystal structure of the complex. [PDF]

open access: yesPLoS ONE, 2013
We report a crystal structure of Hfq and catalase HPII from Escherichia coli. The post-transcriptional regulator Hfq plays a key role in the survival of bacteria under stress.

Models of Hfq interactions with small non-coding RNA in Gram-negative and Gram-positive bacteria

open access: yesFrontiers in Cellular and Infection Microbiology, 2023
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 ...

Prediction of Hfq in actinobacteria [PDF]

open access: yes, 2015
Abstract Hfq 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 ...

Effects of Hfq on the conformation and compaction of DNA [PDF]

open access: yesNucleic Acids Research, 2015
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.

Riboregulators and the role of Hfq in photosynthetic bacteria [PDF]

open access: yesRNA Biology, 2014
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]

open access: yesArchives of Biological Sciences, 2017
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.

Clostridium difficile Hfq can replace Escherichia coli Hfq for most of its function [PDF]

open access: yesRNA, 2014
A gene for the Hfq protein is present in the majority of sequenced bacterial genomes. Its characteristic hexameric ring-like core structure is formed by the highly conserved N-terminal regions. In contrast, the C-terminal forms an extension, which varies in length, lacks homology, and is predicted to be unstructured.
