Figure 5. Structural comparison of the
DNA-binding/transactivation domains of PhoB and OmpR. (a)
Stereoview of a superposition of the structures of the
DNA-binding/transactivation domains of PhoB and OmpR. (b) A
structural comparison of the putative interaction sites of PhoB
and OmpR for RNA polymerase. Each of the loop regions in the HTH
variant motif is colored in yellow. Amino acids that affect the
interaction with RNA polymerase are drawn in red.
