Figure 5

Differential activation by cAMP-CRP can quantitatively explain the sugar utilization hierarchy. a) Plotted is the predicted normalized promoter activity versus the measured one. The two agree well with a correlation coefficient R2 = 0.95, p < 10-10. The error bars are standard errors of 4 biological repeats (x-coordinate error bar) and 95% confidence interval of fits (y-coordinate error bar) b) measured promoter activity (same as figure 1) c) predicted promoter activity from linear fits to CRP input functions of each promoter (data of Fig 4, predicted points removed from data used for fit).
