Correlation of disorder propensities we optimized with various residue scales. R² values are given for residue types marked by closed diamonds (excluding D, E, R, K, H, C, and P, which are marked by open diamonds). a) Nozaki-Tanford side chain transfer energies vs. disorder value; glycine, as the reference amino acid, is given a value of 0; R² = 0.982. b) Kyte-Doolittle hydropathy vs. disorder value; R² = 0.225. c) Russell-Linding coil propensities vs. disorder value; R² = 0.427. d) Radzicka-Wolfenden octanol to water transfer energies vs. disorder value; R² = 0.941. e) Radzicka-Wolfenden cyclohexane to water free energies of transfer vs. disorder value; R² = 0.491. f) Kyte-Doolittle hydropathy vs. Radzicka-Wolfenden cyclohexane to water transfer energies; R² = 0.818. For the entire Nozaki-Tanford subset of residues, R² values are respectively a) 0.977, b) 0.089, c) 0.463, d) 0.881, e) 0.390, f) 0.730.
