(A) The combined ¹⁵N and ¹H chemical shifts perturbations of each resonance for SeR13 between 0.1 and 2.1 mM. (B) The backbone of residues with amide chemical shift perturbations > 0.1 Δ_ppm are shown in red (L19, N26, S27, F28, T29, Y56, D59, F60, I61, S62, and I63). The backbone of residues with amide chemical shift perturbations of < 0.1 but greater than 0.04 Δ_ppm are shown in orange (I4, T9, K16, S18, T29 and D59). Residues that show chemical shifts changes but are overlapped with another crosspeaks are shown in black.
