We report here that the silencing proteins H-NS are the main negative regulators of ompS1 expression in Salmonella .
We report here that the silencing proteins H-NS are the main positive regulators of ompS1 expression in Salmonella .
DNase footprinting was performed to determine the binding of H-NS to the ompS1 regulatory region in the vicinity of -70 to -200 bp upstream E of the P1 transcriptional start .
DNase footprinting was performed to determine the binding of H-NS to the ompS1 regulatory region in the vicinity of OmpR-binding box IV .
Moreover , previous genetic data show that the removal of upstream regions from -310 to -88 gradually caused the derepression of ompS1 expression which , together with Fig. 4D , suggest that H-NS binds at the two nucleation sites .

In addition , our model contemplates that LeuO physically LeuO antagonizes StpA in ompS1 739 does not block the progress of H-NS but rather causes a displacement of H-NS , hence preventing its binding at its polymerization .
