Figure 2
Amino-acid frequencies either side of order-state transition boundaries based on the analysis of the PDB (Table 2[link]). Frequencies based (a) on 1709 order-to-disorder transitions and (b) on 1918 disorder-to-order transitions. A window of five amino acids on either side of the transition boundary was considered and amino-acid frequencies were analyzed with WEBLOGO (Crooks et al., 2004BB8). The height of each stack of single-letter amino-acid codes is proportional to the information content of (i.e. significance of the amino acid at) each residue position, while the height of each individual amino-acid code within a stack is proportional to its relative frequency at the position (see Crooks et al., 2004BB8 for more details). The colouring reflects the classes of amino acids (i.e. charged, aromatic etc.). The order-state transition boundary is indicated by the central gap in each figure.
