Substitutions in the H-NS linker affect gene regulation. (A) L is the linker (amino acids 80–94) and DBD is the DNA binding domain. Original linker residues are in red, additional positive charged residues in blue, alanines in green, and glutamines in black. (B) Swarming motility assay of the linker substitution strains. The relative diameters of the swarm were normalized to the wild-type H-NS (100%). The mean was calculated from three independent experiments with at least two replicates.
