FIG. 2.

Regulatory regions of the characterized ς⁵⁴-dependent genes. The following features are shown for each of the ς⁵⁴-dependent promoters: binding sites for activators, DNA bending proteins (when required), and RNA polymerase. Solid boxes indicate that the binding site has been demonstrated. A hatched box indicates a confirmed binding site, but binding is weak. An open box signifies a proposed binding site. The relative location and orientation of the nearest upstream gene are also shown. All diagrams are to the same scale, except for the hyp operon.
