(A) Predictions of IEL (Inline graphic) for different values of the sawtooth amplitude Inline graphic and plateau height Inline graphic. Inline graphic needs to be as high as 7.3 kcal/mol (>4 base-pair stacks) to match experiment (30). (B) Contour plot of orders of magnitude acceleration (Inline graphic) as a function of (Inline graphic) for Inline graphic kcal/mol and Inline graphic kcal/mol. (C) Scatter plot of Inline graphic versus Inline graphic using all the data in (B). The points plotted show almost no vertical spread, meaning that all points lie on a line. This indicates that Inline graphic is the predictive quantity. Inset: IEL (1.3, 0) and IEL (5.0, 5.0) for a 1-base toehold. The bimolecular initial binding step, which is identical in both landscapes, is marked in orange to highlight the contrast between the landscapes.
