KMnO4 footprinting analysis of the effect of H-NS and StpA on open complex formation of the yghJ promoter. The linear yghJ fragment (−308 to +282) was incubated with 1 U of E. coli RNA polymerase (RNAP) (USB Corp.) in the absence or presence of StpA (500 nM) or H-NS (500 nM). The residues sensitive to oxidation by KMnO4 are indicated. M, GA DNA ladder.
