Fig. 6: Comparison of the lipidic Aβ40 folds with other known structures.
From: Cryo-EM structures of lipidic fibrils of amyloid-β (1-40)
a Superposition of a single protein chain of L1 (blue: protofilaments I and II in different shades of blue), L2 (green), and L3 (orange) Aβ40. The close-up views show regions of similarities and dissimilarities between the three folds. Interactions between residue side chains (shown as stick-model) are depicted as dashed lines. b Backbone traces of the lipidic Aβ40 folds and previously resolved Aβ4013,37 and Aβ4212,36 folds, with residues colored according to the rainbow palette in the lower left corner. Residues with a gray background share a high similarity and the superposition is shown in (c).
