Figure 10.

Definitions of variables and features. (A) Variables were obtained by adding two features shown in the first column. (L,D), (E,D), etc. respectively stand for the combinations of amino acid residues L and D, E and D, etc. The cell of the aromatic-aromatic row and the (L,D) column represents the combination of the aromatic feature of L and the aromatic feature of D shown in the physicochem. section Table (B). For instance, because the values of aromatic-L and aromatic-D are, respectively, 0 and 0, the value of the aromatic-aromatic variable for (L,D) is 0, as shown in bold. (B) Eighteen features were shown as classified into four groups: physicochem., mobility, ss, and ASA. The feature values are given for individual amino acids.
