This book available in PDF, EPUB and Kindle Format. In this study five proteins regulated by quorum sensing are described from the marine bacterium Vibrio fischeri. Each protein is positively regulated by 30C6-HSL and LuxR and negatively regulated at low population density by C8-HSL. Probable LuxR/autoinducer binding sites are found in the promoter regions of the genes encoding each of the proteins. QsrP and RibB are encoded monocistronically, whereas AcfA and QsrV appear to be encoded by a two-gene operon. In competition assays with the parent strain, qsrP and acfA insertion mutants displayed altered colonization phenotypes with the squid symbiotic host. RibB is believed to be an enzyme that catalyzes an initial step of riboflavin synthesis and AcfA is believed to be a pilus subunit protein. The functions of QsrP and QsrV are unknown at this time. Oriented divergently from acfA are open reading frames that code for two putative members of the LysR family of transcriptional regulators. The shared promoter region suggests that transcription of acfA and qsrv may be regulated by one or both of these divergently transcribed proteins. This work defines a quorum-sensing regulon in V. fischeri. A model describing its regulation is presented.

Summary : This book illustrates the importance and significance of Quorum sensing (QS), it’s critical roles in regulating diverse cellular functions in microbes, including bioluminescence, virulence, pathogenesis, gene expression, biofilm formation and antibiotic resistance. Microbes can coordinate population behavior with small molecules called autoinducers (AHL) which serves as a signal of ...

Summary : Genetic studies have shown that the activity of TraR is regulated at the post-translational level by TrIR, a native A. tumefaciens protein that resembles the N-terminal domain of TraR, and an anti-regulator of TraR. I conducted several biochemical studies and showed that TrIR inhibited TraR activity in vitro by forming ...

Summary : Background Bacteria use quorum sensing (QS) circuits to coordinate various activities (among which biofilm formation and the expression of virulence factors) based on the presence of signaling molecules. Different families of signal molecules have been identified in Gram positive and Gram negative bacteria (e.g. autoinducer peptides and acyl homoserine ...

Summary : Quorum sensing (QS) is a process of bacterial cooperative behaviour that has an effect on gene regulation. This cell-to-cell communication system involves the production of signalling molecules according to cell density and growth stage. Virulence, the ability to infest a habitat and cause disease, is also governed by such communication ...
