Hfq Globally Binds and Destabilizes sRNAs and mRNAs in
mSystems, 2019 Hfq is a ubiquitous Sm-like RNA-binding protein in bacteria involved in physiological fitness and pathogenesis, while its in vivo binding nature remains elusive. Here we reported genome-wide Hfq-bound RNAs in Yersinia pestis, a causative agent of plague,

Study of E. coli Hfq's RNA annealing acceleration and duplex destabilization activities using substrates with different GC-contents [PDF]
, 2012 Folding of RNA molecules into their functional three-dimensional structures is often supported by RNA chaperones, some of which can catalyse the two elementary reactions helix disruption and helix formation.

Impact of Hfq on global gene expression and intracellular survival in Brucella melitensis. [PDF]
PLoS ONE, 2013 Brucella melitensis is a facultative intracellular bacterium that replicates within macrophages. The ability of brucellae to survive and multiply in the hostile environment of host macrophages is essential to its virulence. The RNA-binding protein Hfq is

RNA 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.

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

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

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

Prediction of Hfq in actinobacteria [PDF]
, 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 ...
