Figure 3. Differential affinity of H-NS and H-NS_R27 to hilA, proV, and rcsA gene promoters.

Competitive band shift assays showing differential affinity of H-NS_R27 to the hilA and rcsA promoters (A) and to the hilA and proV promoters (B). H-NS and H-NSR₂₇ purified proteins (1, 2, and 4 µM) were incubated with the mixture of both DNA fragments.
