Abstract excerpt
The membrane-bound sensor kinase KdpD and the cytoplasmic response regulator KdpE regulate the expression of the kdpFABC operon coding for the high affinity potassium uptake system KdpFABC in Escherichia coli. The signal transduction cascade of this two component system is activated under K(+)-limiting conditions in the medium, but is less sensitive to high osmolality. In order to test whether K(+) limitation...
