Abstract excerpt

ABSTRACT DksA is a global regulatory protein that, together with the alarmone ppGpp, is required for the "stringent response" to nutrient starvation in the gammaproteobacterium Escherichia coli and for more moderate shifts between growth conditions. DksA modulates the expression of hundreds of genes, directly or indirectly. Mutants lacking a DksA homolog exhibit pleiotropic phenotypes in other gammaproteobacteria...
