CrdS and CrdA Comprise a Two-Component System That Is Cooperatively Regulated by the Che3 Chemosensory System in Myxococcus xanthus
Myxococcus xanthus serves as a model organism for development and complex signal transduction. Regulation of developmental aggregation and sporulation is controlled, in part, by the Che3 chemosensory system. The Che3 pathway consists of homologs to two methyl-accepting chemotaxis proteins (MCPs), CheA, CheW, CheB, and CheR but not CheY. Instead, the output for Che3 is the NtrC homolog CrdA, whi...
متن کاملInduction of beta-lactamase influences the course of development in Myxococcus xanthus.
Myxococcus xanthus is a gram-negative bacterium that develops in response to starvation on a solid surface. The cells assemble into multicellular aggregates in which they differentiate from rod-shaped cells into spherical, environmentally resistant spores. Previously, we have shown that the induction of beta-lactamase is associated with starvation-independent sporulation in liquid culture (K. A...
متن کاملChemosensory regulation of developmental gene expression in Myxococcus xanthus.
The delta-proteobacterium Myxococcus xanthus coordinates its motility during aggregation and fruiting body formation. While searching for chemotaxis genes in M. xanthus, we identified a third chemotaxis-like gene cluster, the che3 cluster, encoding homologs to two methyl-accepting chemotaxis proteins (MCPs), a CheW, a hybrid CheA, a CheB, a CheR, but no CheY. Mutations in mcp3A, mcp3B, and cheA...
متن کاملA vitamin B12-based system for conditional expression reveals dksA to be an essential gene in Myxococcus xanthus.
Myxococcus xanthus is a prokaryotic model system for the study of multicellular development and the response to blue light. The previous analyses of these processes and the characterization of new genes would benefit from a robust system for controlled gene expression, which has been elusive so far for this bacterium. Here, we describe a system for conditional expression of genes in M. xanthus ...
متن کاملHonors Thesis: Characterization of the Che7 System of Myxococcus xanthus through a Yeast Two-Hybrid Assay
Myxococcus xanthus is a Gram negative soil bacterium that utilizes eight chemosensory systems of interacting proteins, most of which are homologous to the E.coli chemotaxis proteins, in order to regulate its two types of gliding motility (A and S), predation of other organisms, and multicellular fruiting body formation. The M. xanthus Che7 system, which has not been thoroughly characterized to ...
