Integral proteins of the extracellular matrix fibrils of Myxococcus xanthus.
The extracellular matrix fibrils of Myxococcus xanthus are mediators of cell-cell cohesion and as such are required for the maintenance of the social lifestyle characteristic of these prokaryotes. The fibrils have also been implicated as factors involved in contact-mediated cell interactions and in signal exchange. The fibrils are extracellular carbohydrate structures with associated proteins. ...
متن کاملExtracellular fibrils and contact-mediated cell interactions in Myxococcus xanthus.
Contact-mediated cell-cell interactions play an important role in the social life-style of Myxococcus xanthus. Previous investigations have demonstrated that fimbriae (also referred to as pili) and extracellular fibrils are involved in these social interactions (L. J. Shimkets, Microbiol. Rev. 54:473-501, 1990). We have used the relatively new technique of low-voltage scanning electron microsco...
متن کاملProteins associated with the Myxococcus xanthus extracellular matrix.
Fruiting body formation of Myxococcus xanthus, like biofilm formation of many other organisms, involves the production of an extracellular matrix (ECM). While the polysaccharide component has been studied, the protein component has been largely unexplored. Proteins associated with the ECM were solubilized from purified ECM by boiling with sodium dodecyl sulfate and were identified by liquid chr...
متن کاملCancer biology: Extracellular proteinases in malignancy
Secreted, matrix-degrading proteinases have been viewed as contributing to tumor metastasis. A recent study indicates that the gene for one of these enzymes, the matrix metalloproteinase stromelysin-1, can actually cause cancer when expressed in transgenic mice.
متن کاملDNA Builds and Strengthens the Extracellular Matrix in Myxococcus xanthus Biofilms by Interacting with Exopolysaccharides
One intriguing discovery in modern microbiology is the extensive presence of extracellular DNA (eDNA) within biofilms of various bacterial species. Although several biological functions have been suggested for eDNA, including involvement in biofilm formation, the detailed mechanism of eDNA integration into biofilm architecture is still poorly understood. In the biofilms formed by Myxococcus xan...
