Fig. 4: The effect of NS132 on HSQC NMR of 15N-labeled αS after incubation with αS fibers.

a A model for the proposed interaction of αS monomer with αS fibers. b The proposed binding interaction sites of αS fibers on the αS monomer residues. The comparison of the HSQC NMR of the 70 µM 15N-labeled αS in the absence (red) and presence (green) of αS fibers after 24 h (c) and 40 h (d). The comparison of the HSQC NMR of the premixed solution of 70 μM 15N-labeled αS + αS fibers in the absence (red) and presence (green) of equimolar NS132 after 24 h (e) and 40 h (f).
