Abstract excerpt
The kdpFABC operon, coding for a high-affinity K(+)-translocating P-type ATPase, is expressed in Escherichia coli as a backup system during K(+) starvation or an increase in medium osmolality. Expression of the operon is regulated by the membrane-bound sensor kinase KdpD and the cytosolic response regulator KdpE. From a nitrogen-fixing cyanobacterium, Anabaena sp. strain L-31, a kdpDgene was cloned (GenBank...
