Figure 1.

Native dimer. (a) Structure and numbering (indicated on each bead) of the type of the bead (as in column 1 of Table 1). (b) Inner (squares)- and inter (dots)-chain contacts. In both figures, the chains A and B are represented in light and dark color, respectively. In our model, the sequences A and B are chosen not to be necessarily equal to explore the relevance of the symmetry of the sequence for protein aggregation.
