Fig 5. Schematic representation of the fold-level relation between FOD classes (hydrophilic: H-2, H-1; hydrophobic: H+2, H+1) and MIR/LIR status of residues from domains belonging to the immunoglobulin-like (A) and flavodoxin (B) folds.

The number of residues of each category is represented by a scaled rectangle area. For example, one should read the top left chart as follows: the number of H+2 and not MIR is 510; the number of MIR and not H+2 is 751; the number of both MIR and H+2 is 305; the number of neither MIR nor H+2 is 4462.
