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.

From ingestion to colonization: the influence of the host environment on regulation of the LEE encoded type III secretion system in enterohaemorrhagic Escherichia coli [PDF]
, 2015 Enterohaemorrhagic Escherichia coli (EHEC) binds to host tissue and intimately attaches to intestinal cells using a dedicated type III secretion system (T3SS). This complex multi-protein organelle is encoded within a large pathogenicity island called the

The contribution of mRNA targeting to spatial protein localization in bacteria
The FEBS Journal, Volume 291, Issue 21, Page 4639-4659, November 2024.mRNA‐based targeting serves as a back‐up strategy for the canonical signal sequence‐based protein targeting in bacteria. While signal sequence‐based targeting depends on dedicated protein‐targeting factors, mRNAs encoding inner membrane proteins can bind directly to protein translocases.

Universality of transverse-momentum resummation and hard factors at the NNLO [PDF]
, 2014 We consider QCD radiative corrections to the production of colourless high-mass systems in hadron collisions. The logarithmically-enhanced contributions at small transverse momentum are treated to all perturbative orders by a universal resummation ...

The RNA Chaperone Hfq Is Involved in Colony Morphology, Nutrient Utilization and Oxidative and Envelope Stress Response in Vibrio alginolyticus. [PDF]
PLoS ONE, 2016 Hfq is a global regulator that is involved in environmental adaptation of bacteria and in pathogenicity. To gain insight into the role of Hfq in Vibrio alginolyticus, an hfq deletion mutant was constructed in V.

Interplay between the catabolite repression control protein Crc, Hfq and RNA in Hfq-dependent translational regulation in Pseudomonas aeruginosa [PDF]
Nucleic Acids Research, 2017 In Pseudomonas aeruginosa the RNA chaperone Hfq and the catabolite repression control protein (Crc) act as post-transcriptional regulators during carbon catabolite repression (CCR). In this regard Crc is required for full-fledged Hfq-mediated translational repression of catabolic genes. RNAseq based transcriptome analyses revealed a significant overlap
