RasA is required for Myxococcus xanthus development and social motility.

چکیده
An insertion in the rasA gene entirely blocked developmental aggregation and sporulation in Myxococcus xanthus while also reducing swarm expansion on a 0.3% agar surface. Data presented here demonstrate that rasA is required for extracellular fibril formation and social gliding motility.

SigF, a new sigma factor required for a motility system of Myxococcus xanthus.
A new sigma factor, SigF, was identified from the social and developmental bacterium Myxococcus xanthus. SigF is required for fruiting body formation during development as well as social motility during vegetative growth. Analysis of gene expression indicates that it is possible that the sigF gene is involved in regulation of an unidentified gene for social motility.
متن کاملMyxococcus xanthus dif genes are required for biogenesis of cell surface fibrils essential for social gliding motility.
Myxococcus xanthus social (S) gliding motility has been previously reported by us to require the chemotaxis homologues encoded by the dif genes. In addition, two cell surface structures, type IV pili and extracellular matrix fibrils, are also critical to M. xanthus S motility. We have demonstrated here that M. xanthus dif genes are required for the biogenesis of fibrils but not for that of type...
متن کاملA chaperone in the HSP70 family controls production of extracellular fibrils in Myxococcus xanthus.
Three independent Tn5-lac insertions in the S1 locus of Myxococcus xanthus inactivate the sglK gene, which is nonessential for growth but required for social motility and multicellular development. The sequence of sglK reveals that it encodes a homologue of the chaperone HSP70 (DnaK). The sglK gene is cotranscribed with the upstream grpS gene, which encodes a GrpE homologue. Unlike sglK, grpS i...
متن کاملTriple mutants uncover three new genes required for social motility in Myxococcus xanthus.
The bacterium Myxococcus xanthus glides over surfaces using two different locomotive mechanisms, called S (social) and A (adventurous) motility that enable cells to move both as groups and as individuals. Neither mechanism involves flagella. The functions of these two motors are coordinated by the activity of a small Ras-like protein, encoded by the mglA gene. The results of previous studies of...
متن کاملA CheW homologue is required for Myxococcus xanthus fruiting body development, social gliding motility, and fibril biogenesis.
In bacteria with multiple sets of chemotaxis genes, the deletion of homologous genes or even different genes in the same operon can result in disparate phenotypes. Myxococcus xanthus is a bacterium with multiple sets of chemotaxis genes and/or homologues. It was shown previously that difA and difE, encoding homologues of the methyl-accepting chemoreceptor protein (MCP) and the CheA kinase, resp...
