On the facultative requirement of the bacterial RNA chaperone, Hfq [PDF]

Trends in Microbiology, 2009
The pleiotropic post-transcriptional regulator Hfq is an RNA chaperone that facilitates pairing interactions between small regulatory RNAs (sRNAs) and their mRNA targets in several bacteria. However, this classical pattern, derived from the Escherichia coli model, is not applicable to the whole bacterial kingdom.

The Quorum Sensing Regulated sRNA Lrs1 Is Involved in the Adaptation to Low Iron in Pseudomonas aeruginosa

Environmental Microbiology Reports, Volume 17, Issue 2, April 2025.
The quorum sensing regulated sRNA Lrs1 participates in the adaptation of Pseudomonas aeruginosa in low iron by downregulating the siderophore pyochelin, the Quorum Sensing system PQS, and its associated virulence factor phenazines. ABSTRACT Iron is an essential nutrient for microbial growth. The opportunistic pathogen Pseudomonas aeruginosa can survive

Twofold Video Hashing with Automatic Synchronization

, 2014
Video hashing finds a wide array of applications in content authentication, robust retrieval and anti-piracy search. While much of the existing research has focused on extracting robust and secure content descriptors, a significant open challenge still ...

Identification, characterization and classification of prokaryotic nucleoid‐associated proteins

Molecular Microbiology, Volume 123, Issue 3, Page 206-217, March 2025.
Nucleoid‐associated proteins (NAPs) structure DNA by either bending, wrapping, bridging, or forming protein filaments on the DNA. We review newly identified NAPs and provide a list of simple biochemical assays to study the DNA‐structuring properties of novel NAPs. Abstract Common throughout life is the need to compact and organize the genome.

Distinctive Regulation of Carbapenem Susceptibility in Pseudomonas aeruginosa by Hfq

Frontiers in Microbiology, 2020
Carbapenems are often the antibiotics of choice to combat life threatening infections caused by the opportunistic human pathogen Pseudomonas aeruginosa. The outer membrane porins OprD and OpdP serve as entry ports for carbapenems.

Discovery of high-frequency quasi-periodic oscillations in the black-hole candidate IGR J17091-3624

, 2012
We report the discovery of 8.5 sigma high-frequency quasi-periodic oscillations (HFQPOs) at 66 Hz in the RXTE data of the black hole candidate IGR J17091-3624, a system whose X-ray properties are very similar to those of microquasar GRS 1915+105.

Chromatin and gene regulation in archaea

Molecular Microbiology, Volume 123, Issue 3, Page 218-231, March 2025.
Recent data from diverse archaea with different repertoires of nucleoid‐associated proteins show a common genome‐wide chromatin organisation where chromatin maintains access to gene promoters independently of transcription activity. Abstract The chromatinisation of DNA by nucleoid‐associated proteins (NAPs) in archaea ‘formats’ the genome structure in ...

Deletion of the small RNA chaperone protein Hfq down regulates genes related to virulence and confers protection against wild-type Brucella challenge in mice

Frontiers in Microbiology, 2016
Brucellosis is one of the most common zoonotic epidemics worldwide. Brucella, the etiological pathogen of brucellosis, has unique virulence characteristics, including the ability to survive within the host cell.

The RNA chaperone Hfq has a multifaceted role in Edwardsiella ictaluri

Frontiers in Cellular and Infection Microbiology
Edwardsiella ictaluri is a Gram-negative, facultative intracellular bacterium that causes enteric septicemia in catfish (ESC). The RNA chaperone Hfq (host factor for phage Qβ replication) facilitates gene regulation via small RNAs (sRNAs) in various ...
