Structural consequences of Ser modification in mature httNTQ37P10K2 aggregates. (a) Fraction of molecules cleaved within httNT after exposure to trypsin in various mature aggregates (WT, black bars; S13pS/S16pS, blue bars; S13D/S16D, red bars; S13pS, red hatched bar; S16pS, blue hatched bar). (b) Sedimentation assays of aggregation kinetics and plateau levels of monomer for WT (●), S13D/S16D (♦) and S13pS/S16pS (▲) peptides in PBS at 37 °C. Inset: Dissociation of S13D/S16D aggregates in PBS at 37 °C by sedimentation assay.
