Figure 2.

(top) Dependence of ln(C) on the DA distance R_DA where C = 〈H_DA〉² /〈H_DA²〉 = [1 + (σ² /〈H_DA〉²)]⁻¹. The dot-dash line denotes the value of C where 〈H_DA〉² = σ² (bottom) $V=\sqrt{\text{var}[<H_{DA}^2(R_{DA})>]}/\mathit{\text{avg}}[<H_{DA}^2(R_{DA})>]$ (“Scatter”) vs distance. V of the scale of unity indicates that the specific protein structure largely determines the observable rate.³¹
