Fig. 4.

Thermal distribution of the number of residues N(L_s) involved in β -strands of the length L_s in bound Aβ peptides. Filled and empty bars correspond to the MT and the WT, respectively. The inset shows the ratio N_{W T} (L_s)/N_MT (L_s) as a function of L_s, where N_{W T} (L_s) and N_MT (L_s) are computed for the WT and MT. The figure indicates that long β-strands occur less frequently in the MT Aβ peptides bound to the fibril than in the WT. The distributions N(L_s) are computed at 360K.
