Figure 3From: From biophysics to evolutionary genetics: statistical aspects of gene regulationTranscription factor binding energies of the E. coli genome. (a) Energy "landscape" E(r) for specific binding of the CRP factor at 200 consecutive positions r in an intergenic region, with a binding site at position 59. (b) Count histogram Wdat(E) with energy bins of width 0.1 obtained from all intergenic regions, together with the distribution W0(E) for a random sequence (dashed line, shown with a 30 fold zoom into the region E < 14).
