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.

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 ...

Unnatural Amino Acid and Emerging Chemistry Approaches to Map RNA–Protein Interactions

open access: yesAngewandte Chemie, EarlyView.
This review highlights emerging chemistries for mapping RNA–protein interactions, including genetically encoded unnatural amino acids, novel photocrosslinkers, and non‐photoactivatable crosslinking systems. We compare their mechanisms, reactivity and applications, outlining how these next‐generation tools enable higher‐resolution, site‐specific ...

Functional Characterization of Acinetobacter baumannii Lacking the RNA Chaperone Hfq

open access: yesFrontiers in Microbiology, 2017
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 ...

The Pseudomonas aeruginosa CrcZ RNA interferes with Hfq-mediated riboregulation.

open access: yesPLoS ONE, 2017
The RNA chaperone Hfq regulates virulence and metabolism in the opportunistic pathogen Pseudomonas aeruginosa. During carbon catabolite repression (CCR) Hfq together with the catabolite repression control protein Crc can act as a translational repressor ...

The Pleiotropic Phenotypes Caused by an hfq Null Mutation in Vibrio harveyi

open access: yesMicroorganisms, 2023
Hfq is a global regulator and can be involved in multiple cellular processes by assisting small regulatory RNAs (sRNAs) to target mRNAs. To gain insight into the virulence regulation of Hfq in Vibrio harveyi, the hfq null mutant, ∆hfq, was constructed in

Hfq C-terminal region forms a β-rich amyloid-like motif without perturbing the N-terminal Sm-like structure

open access: yesCommunications Biology, 2023
Hfq is a pleitropic actor that serves as stress response and virulence factor in the bacterial cell. To execute its multiple functions, Hfq assembles into symmetric torus-shaped hexamers.

The Escherichia coli Hfq protein: an unattended DNA-transactions regulator

open access: yesFrontiers in Molecular Biosciences, 2016
The Hfq protein was discovered in Escherichia coli as a host factor for bacteriophage Qβ RNA replication. Subsequent studies indicated that Hfq is a pleiotropic regulator of bacterial gene expression.

Association of RNAs with Bacillus subtilis Hfq. [PDF]

open access: yesPLoS ONE, 2013
The prevalence and characteristics of small regulatory RNAs (sRNAs) have not been well characterized for Bacillus subtilis, an important model system for Gram-positive bacteria. However, B.
