Extended Data Fig. 2: Additional proteinaceous fragment in different heparin-remodelled α-syn fibril polymorphs and conformational changes of the Hep-remod-3 fibril.

a. Local structures of heparin-remodelled α-syn fibril polymorphs. Models near fragment 14-22/25 are shown in sticks. b. Structural comparison of apo and Hep-remod-3. Flipped residues are shown in sticks.
