H-NS is an abundant structural component of bacterial chromatin and influences many cellular processes, including recombination, transposition, and transcription. We have studied the mechanism of action of H-NS at the osmotically regulated proU promoter. The interaction of H-NS with a curved DNA element located downstream of the proU promoter is required(More)
Changes in DNA supercoiling in response to environmental signals such as osmolarity, temperature, or anaerobicity appear to play an underlying role in the regulation of gene expression in bacteria. Extensive genetic analyses have implicated the osmZ gene in this regulatory process: osmZ mutations are highly pleiotropic and alter the topology of cellular(More)
