An upstream Hfq binding site in the fhlA mRNA leader region facilitates the OxyS-fhlA interaction.

PLoS ONE, 2010
BackgroundTo survive, bacteria must be able to adapt to environmental stresses. Small regulatory RNAs have been implicated as intermediates in a variety of stress-response pathways allowing dynamic gene regulation. The RNA binding protein Hfq facilitates

Conditional Hfq Association with Small Noncoding RNAs in Pseudomonas aeruginosa Revealed through Comparative UV Cross-Linking Immunoprecipitation Followed by High-Throughput Sequencing

mSystems, 2019
Bacterial small noncoding RNAs (sRNAs) play posttranscriptional regulatory roles in cellular responses to changing environmental cues and in adaptation to harsh conditions. Generally, the RNA-binding protein Hfq helps sRNAs associate with target mRNAs to

Pleiotropic regulatory function of the RNA chaperone Hfq in the Pseudomonas protegens FD6

Phytopathology Research
The rhizosphere bacterium Pseudomonas protegens FD6, which is associated with the production of antibiotics such as pyoluteorin (PLT) and 2,4-diacetylphloroglucinol (2,4-DAPG), has strong antagonistic effects on phytopathogens.

The X-ray Outburst of H1743-322: High-Frequency QPOs with a 3:2 Frequency Ratio

, 2004
We observed the 2003 X-ray outburst of H1743-322 in a series of 130 pointed observation with RXTE. We searched individual observations for high-frequency QPOs (HFQPOs) and found only weak or marginal detections near 240 and 160 Hz.

Impact of Hfq on the intrinsic drug resistance of Salmonella enterica serovar Typhimurium

Frontiers in Microbiology, 2012
Salmonella enterica is an important enteric pathogen, and its various serovars cause both systemic and intestinal diseases in humans and domestic animals.

Lagrangian matching invariants for fibred four-manifolds: I

, 2007
In a pair of papers, we construct invariants for smooth four-manifolds equipped with `broken fibrations' - the singular Lefschetz fibrations of Auroux, Donaldson and Katzarkov - generalising the Donaldson-Smith invariants for Lefschetz fibrations.

Acidic C-terminal domains autoregulate the RNA chaperone Hfq

eLife, 2017
The RNA chaperone Hfq is an Sm protein that facilitates base pairing between bacterial small RNAs (sRNAs) and mRNAs involved in stress response and pathogenesis. Hfq possesses an intrinsically disordered C-terminal domain (CTD) that may tune the function
