Bacillus subtilis Chemotaxis
We are investigating chemotaxis in the model Gram-positive bacterium Bacillus subtilis. While Escherichia coli has long been the paradigm for bacterial chemotaxis, the pathway architecture is not conserved in other species of bacteria. Interestingly, B. subtilis behaves in an identical manner to E. coli with regards to chemotaxis. The pathways in the two bacteria also have homologous proteins. Yet, how these proteins are “wired” to one another in the two pathways is entirely different. We seek to understand why these two pathways are “wired” differently and the extent of degeneracy in the basic design.
