Fig. 5: Electrostatic interactions in α-syn fibril polymorphs.

Primary sequence of WT α-syn fibril core (FC) is shown on top. K residues are colored in blue; H is light blue; E/D is red. Interacting charged residues in the structures of different α-syn polymorphic fibrils are connected with solid lines. One layer of different polymorphic structures of α-syn fibrils are shown below. The dimeric α-syn molecules are colored in different levels of gray. Electrostatic interactions are highlighted with K colored in blue, H in light blue and E in red. PDB IDs of the structures are provided in parentheses.
