Molecular characterization, nucleotide sequence, and expression of the fliO, fliP, fliQ, and fliR genes of Escherichia coli.
The fliL operon of Escherichia coli contains seven genes that are involved in the biosynthesis and functioning of the flagellar organelle. DNA sequences for the first three genes of this operon have been reported previously. A 2.2-kb PstI restriction fragment was shown to complement known mutant alleles of the fliO, fliP, fliQ, and fliR genes, the four remaining genes of the fliL operon. Four o...
متن کاملThe Flagellar Regulator fliT Represses Salmonella Pathogenicity Island 1 through flhDC and fliZ
Salmonella pathogenicity island 1 (SPI1), comprising a type III section system that translocates effector proteins into host cells, is essential for the enteric pathogen Salmonella to penetrate the intestinal epithelium and subsequently to cause disease. Using random transposon mutagenesis, we found that a Tn10 disruption in the flagellar fliDST operon induced SPI1 expression when the strain wa...
متن کاملTwo novel regulatory genes, fliT and fliZ, in the flagellar regulon of Salmonella.
The flagellar operons of Salmonella are divided into three classes with respect to their transcriptional hierarchy. Expression of the class 2 operons requires the class 1 gene products, FlhD and FlhC, and is increased by mutation in the flgM gene, which encodes a class 3-specific anti-sigma factor. Here we report the identification of two novel regulatory genes for class 2 transcription. Presen...
متن کاملCaulobacter FliQ and FliR membrane proteins, required for flagellar biogenesis and cell division, belong to a family of virulence factor export proteins.
The Caulobacter crescentus fliQ and fliR genes encode membrane proteins that have a role in an early step of flagellar biogenesis and belong to a family of proteins implicated in the export of virulence factors. These include the MopD and MopE proteins from Erwinia carotovora, the Spa9 and Spa29 proteins from Shigella flexneri, and the YscS protein from Yersinia pestis. Inclusion in this family...
متن کاملMolecular characterization of a flagellar export locus of Helicobacter pylori.
Motility of Helicobacter species has been shown to be essential for successful colonization of the host. We have investigated the organization of a flagellar export locus in Helicobacter pylori. A 7-kb fragment of the H. pylori CCUG 17874 genome was cloned and sequenced, revealing an operon comprising an open reading frame of unknown function (ORF03), essential housekeeping genes (ileS and murB...
