(A) Logarithm of the square of the norm of the allosteric response, ||dRa||2, is shown as function of the logarithm of the number of residues, N. The solid line corresponds to ∼ N. (B) The logarithm of the stiffness ka as a function of the logarithm of the number of residues N is given. The solid line represents the theoretical prediction ∼ 1/N. In both plots, r indicates the Pearson coefficient. To see this figure in color, go online.
