Comparison of the 13C secondary chemical shifts obtained in the present work with previous studies of Aβ42 fibrils. The difference between the 13Cα and 13Cβ secondary chemical shifts of the Aβ42 fibril obtained in this study was plotted against that of the fibrils reported by (a) Xiao et al.,27 (b) Colvin et al.,28, 58 (c) Ravotti et al.,29, 59 and (d) Gremer et al.14 The reported structures of the fibrils are shown in the insets; their PDB identifiers are (a) 2MXU , (b) 5KK3, (c) 2NAO and (d) 5OQV. For comparison, the difference between the 13Cα and 13Cβ secondary chemical shifts of the Aβ42 fibril of Xiao et al.27 was plotted against those reported by (e) Colvin et al.28, 58 and (f) Ravotti et al.29, 59 The corresponding plots show excellent linearity, suggesting that the Aβ42 structures of these studies are very similar to each other.
