Role of IHF on P styA activity. β-galactosidase activities disclosed by E. coli strains carrying the pPR9TT-derivative plasmids indicated below the histogram. The β-galactosidase assays were carried out on cells grown in LB medium at 37°C to an A600 ≅ 2.0. Standard deviations (vertical lines) are based on the mean values of five independent experiments.
