Overexpression of an outer membrane protein associated with decreased susceptibility to carbapenems in Proteus mirabilis. [PDF]
PLoS ONE, 2015 Proteus mirabilis isolates commonly have decreased susceptibility to imipenem. Previously, we found P. mirabilis hfq mutant was more resistant to imipenem and an outer membrane protein (OMP) could be involved.

Identifying and characterizing Hfq–RNA interactions [PDF]
Methods, 2013 To regulate stress responses and virulence, bacteria use small regulatory RNAs (sRNAs). These RNAs can up or down regulate target mRNAs through base pairing by influencing ribosomal access and RNA decay. A large class of these sRNAs, called trans-encoded sRNAs, requires the RNA binding protein Hfq to facilitate base pairing between the regulatory RNA ...

Involvement of the post-transcriptional regulator Hfq in Yersinia pestis virulence. [PDF]
PLoS ONE, 2009 BACKGROUND:Yersinia pestis is the causative agent of plague, which is transmitted primarily between fleas and mammals and is spread to humans through the bite of an infected flea or contact with afflicted animals.

Hfq binding changes the structure of Escherichia coli small noncoding RNAs OxyS and RprA, which are involved in the riboregulation of rpoS [PDF]
, 2013 OxyS and RprA are two small noncoding RNAs (sRNAs) that modulate the expression of rpoS, encoding an alternative sigma factor that activates transcription of multiple Escherichia coli stress-response genes. While RprA activates rpoS for translation, OxyS

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.

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.

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

The metabolic enzyme AdhE controls the virulence of Escherichia coli O157:H7 [PDF]
, 2014 Classical studies have focused on the role that individual regulators play in controlling virulence gene expression. An emerging theme, however, is that bacterial metabolism also plays a key role in this process.
