Search efficiency in E. coli with "weakened" CRP sites. Mean ROC curves for the R
search method trying to locate CRP binding sites on the E. coli genome, using the original, asymmetric and mirrored collections of CRP. The plot is scaled to encompass a 1/10 true to false positive ratio for CRP (2100 false positives). The R
profile of the original, asymmetrical and mirrored CRP motifs is shown in the inset.
