SprB is a cell surface component of the Flavobacterium johnsoniae gliding motility machinery.
Cells of the gliding bacterium Flavobacterium johnsoniae move rapidly over surfaces by an unknown mechanism. Transposon insertions in sprB resulted in cells that were defective in gliding. SprB is a highly repetitive 669-kDa cell surface protein, and antibodies against SprB inhibited the motility of wild-type cells. Polystyrene microspheres coated with antibodies against SprB attached to and we...
متن کاملNovel features of the polysaccharide-digesting gliding bacterium Flavobacterium johnsoniae as revealed by genome sequence analysis.
The 6.10-Mb genome sequence of the aerobic chitin-digesting gliding bacterium Flavobacterium johnsoniae (phylum Bacteroidetes) is presented. F. johnsoniae is a model organism for studies of bacteroidete gliding motility, gene regulation, and biochemistry. The mechanism of F. johnsoniae gliding is novel, and genome analysis confirms that it does not involve well-studied motility organelles, such...
متن کاملNon-contiguous finished genome sequence and description of the gliding bacterium Flavobacterium seoulense sp. nov.
Flavobacterium seoulense strain EM1321(T) is the type strain of Flavobacterium seoulense sp. nov., a proposed novel species within the genus Flavobacterium. This strain is a Gram-reaction-negative, aerobic, rod-shaped bacterium isolated from stream water in Bukhansan National Park, Seoul. This organism is motile by gliding. Here, we describe the features of Flavobacterium seoulense EM1321(T), t...
متن کاملPopulation structure of the fish-pathogenic bacterium Flavobacterium psychrophilum.
Flavobacterium psychrophilum is currently one of the main bacterial pathogens hampering the productivity of salmonid farming worldwide, and its control mainly relies on antibiotic treatments. To better understand the population structure of this bacterium and its mode of evolution, we have examined the nucleotide polymorphisms at 11 protein-coding loci of the core genome in a set of 50 isolates...
متن کاملFlavobacterium johnsoniae RemA is a mobile cell surface lectin involved in gliding.
Cells of Flavobacterium johnsoniae move rapidly over surfaces by a process known as gliding motility. Gld proteins are thought to comprise the motor that propels the cell surface adhesin SprB. Cells with mutations in sprB are partially defective in motility and are also resistant to some bacteriophages. Transposon mutagenesis of a strain carrying a deletion spanning sprB identified eight mutant...
