The Role of Host Hormones and Metabolites in the Regulation of Virulence in Enterohemorrhagic Escherichia coli (EHEC)
… signals, and use them as cues for differential gene regulation and niche adaptation. This allows for a temporal and energy efficient up-regulation of EHEC virulence factors that is essential for successful colonization and infection of the host. These virulence factors include motility genes, …

Environmental sensing and response of conserved RNA-processing machines to specific external chemical cues
… cell, whose primary function is to translate the genetic code from mRNA to protein; however, it also maintains the capacity to respond to small molecule inducers and regulatory elements to influence expression of nearby genes. Polynucleotide phosphorylase (PNPase) is a homotrimeric protein whose …

Amino Acid Residues in LuxR Critical for its Mechanism of Transcriptional Activation during Quorum Sensing
… for a mechanism of cell-density dependent bacterial gene regulation known as quorum sensing. During quorum sensing in <I>V. fischeri</I>, an acylated homoserine chemical signal (autoinducer) is synthesized by the bacteria and used to sense their own species in a given environment. As the …

Roles of Small Rnas and Paralogous Proteins In Bacillus Anthracis Virulence Gene Regulation
… a myriad of regulatory mechanisms to control gene expression. One of the most common mechanisms is post-transcriptional control through the function of small regulatory RNAs (sRNAs). Small regulatory RNAs (sRNAs) are short transcripts that base-pair to mRNA targets or interact with regulatory …

Target regulation and prioritization by the small RNA SgrS in Escherichia coli
Regulation of gene expression by small non-coding RNAs is ubiquitous in all domains of life. In bacteria, small RNAs are known regulators of various stress responses. Diverse mechanisms employed by small RNAs demonstrate multi-faceted nature of gene regulation, tailored to respond to stress with …
