Fig. 3. Secondary ¹³C′ (A), ¹³C^α (B), ¹³C^β (C), and ¹⁵N (D) chemical shifts of the β-LG_11–20 fibrils. The secondary shifts were calculated as Δδ = δ(exp) − δ(X), where δ(exp) is the experimentally observed chemical shift of either the monomer values in liquid, M(aq), monomer in solid state, M(s), or for the fibrils, F(s), whereas δ(X) represents the Wishart⁴⁹ random coil values in ppm. The secondary ¹³C′ and ¹⁵N shifts for D1, Q3, K4, W9, Y10 could not be calculated as the residues were not labelled in any of the samples.
