Guanosine tetraphosphate (ppGpp) dependence of the growth rate control of rrnB P1 promoter activity in Escherichia coli.

The Journal of biological chemistry - 15 Jul 1990

Hernandez V J, Bremer H

Abstract excerpt

We have fused the ribosomal RNA promoter P1 from the rrnB gene of Escherichia coli to lacZ and examined its guanosine tetraphosphate (ppGpp)-dependent expression at different growth rates. The rrnB P1-lacZ fusion was constructed on plasmid vectors and then recombined into the chromosome of a delta lac relA1 strain close to the normal location of the rrnB locus and in the normal orientation, coincident with the...
