σE in-vitro active promoter mix-and-matching: Correlations between the promoter elements, for the in-vitro active promoters, are shown in the figure panels. The promoter elements whose strengths are correlated are, for each panel, indicated on the axes. The correlation constants and P values are also indicated for each panel. Strengths of individual promoter elements are estimated by the corresponding weight matrix scores (see Methods). Note that the total promoter strength, and dsDNA binding strength, correspond, respectively, to the sum of all the element strengths (Eq. 1.7), and the sum of the element strengths involved in dsDNA binding (Eq. 1.6) – with the element involved in the correlation excluded from the sum. The first row correspond to the correlation of the dsDNA and ssDNA interacting elements; the second row to the correlations between dsDNA interacting elements and the total promoter strength; the third row to the mutual correlations of dsDNA interacting elements
