The end-to-end distribution P (Ree) for different values of the interaction energy ε, calculated as described in text following eqn (6) for a protein of 64 amino acids. Arrow indicates direction of growth of ε. As ε increases, the average distance shortens and the distribution becomes narrower. Sample chain configurations at low ε and high ε are shown as insets. P (Ree) can be used to calculate average FRET efficiency as a function of ε using eqn (5).
