Engineering Vibrio fischeri for Inducible Gene Expression
The marine bacterium Vibrio fischeri serves as a model organism for a variety of natural phenomena, including symbiotic host colonization. The ease with which the V. fischeri genome can be manipulated contributes greatly to our ability to identify the factors involved in these phenomena. Here, we have adapted genetic tools for use in V. fischeri to promote our ability to conditionally control t...
متن کاملLuxO controls luxR expression in Vibrio harveyi: evidence for a common regulatory mechanism in Vibrio.
Quorum-sensing control of luminescence in Vibrio harveyi, which involves an indirect autoinducer-mediated phosphorelay signal transduction system, contrasts with the prototypical quorum-sensing system of Vibrio fischeri, in which the autoinducer and the transcriptional activator LuxR directly activate lux operon expression. In V. harveyi, a regulator not homologous to V. fischeri LuxR and also ...
متن کاملIn silico Prediction and Docking of Tertiary Structure of LuxI, an Inducer Synthase of Vibrio fischeri
Background: LuxI is a component of the quorum sensing signaling pathway in Vibrio fischeri responsible for the inducer synthesis that is essential for bioluminescence. Methods: Homology modeling of LuxI was carried out using Phyre2 and refined with the GalaxyWEB server. Five models were generated and evaluated by ERRAT, ANOLEA, QMEAN6, and Procheck. Results: Five refined models were gener...
متن کاملQuorum regulation of luminescence in Vibrio fischeri.
Luminescence in Vibrio fischeri is controlled by a population density-responsive regulatory mechanism called quorum sensing. Elements of the mechanism include: LuxI, an acyl-homoserine lactone (acyl-HSL) synthase that directs synthesis of the diffusible signal molecule, 3-oxo-hexanoyl-HSL (V. fischeri autoinducer-1, VAI-1); LuxR, a transcriptional activator protein necessary for response to VAI...
متن کاملExpression of Recombinant Protein B Subunit Pili from Vibrio Cholera
Background & Aims: Vibrio cholerae is a gram-negative bacterial pathogen that causes cholera disease. Following ingestion by a host and entry into the upper intestine, V. cholera colonizes and begins to emit enterotoxin. One of the most pathogenic factors of Vibrio cholera is toxin-coregulated pili (TCP). ToxinCoregulated pili is as the primary factor requiered for the colonization and insisten...
