Multiple mechanisms contribute to osmotic inducibility of proU operon expression in Escherichia coli: demonstration of two osmoresponsive promoters and of a negative regulatory element within the first structural gene.
Transcription of the proU operon in Escherichia coli is induced several hundredfold upon growth of cells in media of elevated osmolarity. A low-copy-number promoter-cloning plasmid vector, with lacZ as the reporter gene, was used for assaying the osmoresponsive promoter activity of each of various l...
