444 Post-translational role of RNA modifications in sRNA chaperone Hfq
OBJECTIVES/GOALS: The goal of this study is to determine the role of the tRNA modifications in the translation of Hfq. Hfq is an RNA chaperone that acts as a co-factor for the action of the largest class of small RNAs in E. coli.

The RNA chaperone Hfq impacts growth, metabolism and production of virulence factors in Yersinia enterocolitica. [PDF]
To adapt to changes in environmental conditions, bacteria regulate their gene expression at the transcriptional but also at the post-transcriptional level, e.g. by small RNAs (sRNAs) which modulate mRNA stability and translation.

Hfq is a global regulator that controls the pathogenicity of Staphylococcus aureus. [PDF]
The Hfq protein is reported to be an RNA chaperone, which is involved in the stress response and the virulence of several pathogens. In E. coli, Hfq can mediate the interaction between some sRNAs and their target mRNAs.

RNA reflections: converging on Hfq [PDF]
As the journal RNA celebrates its 20th anniversary, the role of non-coding RNAs as regulators is firmly established in a broad range of organisms. Among these are the many bacterial RNAs that pair with their targets and regulate mRNA stability and translation. In Escherichia coli and other gram-negative organisms, these small RNAs (sRNAs) depend on Hfq,

Hfq: the flexible RNA matchmaker [PDF]
The RNA chaperone protein Hfq is critical to the function of small, base pairing RNAs in many bacteria. In the past few years, structures and modeling of wild type Hfq and assays of various mutants have documented that the homohexameric Hfq ring can contact RNA at four sites (proximal face, distal face, rim and C-terminal tail) and that different RNAs ...

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.

Profound impact of Hfq on nutrient acquisition, metabolism and motility in the plant pathogen Agrobacterium tumefaciens. [PDF]
As matchmaker between mRNA and sRNA interactions, the RNA chaperone Hfq plays a key role in riboregulation of many bacteria. Often, the global influence of Hfq on the transcriptome is reflected by substantially altered proteomes and pleiotropic ...

Hfq-licensed RNA–RNA interactome in Pseudomonas aeruginosa reveals a keystone sRNA
Significance Hfq is a key posttranscriptional regulator that modulates base-pairing interactions between sRNAs and their target mRNAs. Although there are more than 100 different sRNAs in Pseudomonas aeruginosa, information on their regulatory targets was

Overexpression of an outer membrane protein associated with decreased susceptibility to carbapenems in Proteus mirabilis. [PDF]
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.
