The Characterization of the Fucose Sensing Kinase (FUSK) and the Fucose Sensing Response Regulator (FUSR) and Their Role in Virulence Regulation in Enterohemorrhagic Escherichia Coli O157:H7
… signaling cascade. The two-component systems QseBC and QseEF are at the core of the AI-3/Epi/NE signaling, controlling expression of flagellar motility genes, the LEE and type 3 secreted effectors in response to AI-3 and the catecholamine hormones Epi and NE. The network of regulatory proteins …

The Functional Characterization of the LysR-Type Transcriptional Regulator QseD and the SorC-Type Transcriptional Regulator LsrR in Enterohemorrhagic Escherichia coli
… through two two-component systems QseBC and QseEF, and abiotic environmental cues, such as phosphate and sulfate levels through QseEF [1-2]. Additionally, quorum sensing (QS) signaling cascades have evolved to sense microbial population density and diversity through the recognition …

The Characterization of Quorum Sensing E. Coli Regulators E,F, and G (Qse EFG) and Their Role in Pathogenesis
… and involves the two-component sytem QseBC. Less is known about the signaling towards EHEC's AE lesion formation capability. Here, we describe a unique signaling system important for EHEC pedestal formation. In contrast to conventional two-component signaling systems, this one consists …

Evidence of Water to Human Transmission of Aeromonas Hydrophila: Critical Role of Quorum Sensing in Bacterial Virulence & Host Response
… and characterized a new two-component based QseBC/AI-3 QS system in A. hydrophila SSU by generating a ΔqseB mutant. We noted that deletion of the qseB gene attenuated bacterial virulence in a septicemic mouse model of infection, had diminished swimming and swarming motility, and the mutant …

Post-Transcriptional Regulation of Virulence Genes by GlmY and GlmZ in Enterohemorrhagic E. Coli
… The two two-component systems QseEF and QseBC have been previously shown to regulate various virulence genes. We established that these systems both regulate the transcription of the small RNA (sRNA) glmY. GlmY is known to stabilize another sRNA, GlmZ, which activates the translation of …
