sX13 activity does not require Hfq.
, 2013 (A) Northern blot analysis. Total RNA from NYG-grown Xcv strains 85-10 (wt), the hfq frameshift mutant (hfq−) and the hfq mutant ectopically expressing Hfq (phfq) was analyzed using sX13- or sX14-specific probes.

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.We characterised nine SPFH‐domain containing proteins in Pseudomonas aeruginosa PA14 and found remarkable sequence divergence and scattered evolutionary distribution. Functional analyses showed that single or multiple deletions had no detectable impact on growth, motility, biofilm formation, stress resistance or virulence under laboratory conditions ...

Molecular Plant Pathology, Volume 27, Issue 4, April 2026.This study revealed that the transcriptional regulator EmrR in Dickeya oryzae modulates virulence by regulating hrpL expression and c‐di‐GMP levels. It affects motility, biofilm formation, cellulase production and pathogenicity. EMSA and footprinting confirmed EmrR binds directly to the promoter of its target operon.

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.

Hfq regulates the expression of the thermostable direct hemolysin gene in
BMC Microbiology, 2008 Background The hfq gene is conserved in a wide variety of bacteria and Hfq is involved in many cellular functions such as stress responses and the regulation of gene expression.

Identification of the Hfq-binding site on DsrA RNA: Hfq binds without altering DsrA secondary structure [PDF]
RNA, 2003 DsrA RNA regulates the translation of two global regulatory proteins in Escherichia coli. DsrA activates the translation of RpoS while repressing the translation of H-NS. The RNA-binding protein Hfq is necessary for DsrA to function in vivo. Although Hfq binds to DsrA in vitro, the role of Hfq in DsrA-mediated regulation is not known.

Advanced Science, Volume 13, Issue 12, 27 February 2026.To precisely modulate natural and synthetic regulatory parts, SUPER is introduced as a sophisticated and tunable controller of genetic devices without requiring sequence modification on the target. SUPER enhances dynamic range of RNA‐, chemical‐, temperature‐, and protein‐responsive biosensors up to 1011%, and converts biosensors to cover an expanded ...

Molecular Microbiology, Volume 125, Issue 2, Page 108-122, February 2026.Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.

Positive regulation by small RNAs and the role of Hfq [PDF]
Proceedings of the National Academy of Sciences, 2010 Bacterial small noncoding RNAs carry out both positive and negative regulation of gene expression by pairing with mRNAs; in Escherichia coli , this regulation often requires the RNA chaperone Hfq. Three small regulatory RNAs (sRNAs), DsrA, RprA, and ArcZ, positively regulate translation of the sigma factor RpoS ...
