Natural transformation of Vibrio fischeri requires tfoX and tfoY.
Recent evidence has indicated that natural genetic transformation occurs in Vibrio cholerae, and that it requires both induction by chitin oligosaccharides, like chitohexaose, and expression of a putative regulatory gene designated tfoX. Using sequence and phylogenetic analyses we have found two tfoX paralogues in all sequenced genomes of the genus Vibrio. Like V. cholerae, when grown in chitoh...
متن کاملCharacterizing the Regulation of tfoX in Vibrio fischeri
Natural transformation describes how some bacteria can incorporate exogenous DNA into their genome and acquire new traits. This phenomenon occurs in Vibrios and is induced by the biopolymer chitin. In Vibrios, TfoX is a primary regulator of natural transformation. The mechanisms underlying chitin-induced natural transformation and activation of TfoX in Vibrio fischeri remain unclear. This proje...
متن کاملIndependent Regulation of Type VI Secretion in Vibrio cholerae by TfoX and TfoY
Type VI secretion systems (T6SSs) are nanomachines used for interbacterial killing and intoxication of eukaryotes. Although Vibrio cholerae is a model organism for structural studies on T6SSs, the underlying regulatory network is less understood. A recent study showed that the T6SS is part of the natural competence regulon in V. cholerae and is activated by the regulator TfoX. Here, we identify...
متن کاملcompactifications and representations of transformation semigroups
this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...
15 صفحه اولIn 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...
