Figure 8.

(Left) Picture of an isolated (AG)_n chain with type II β-turn structure. (Right) Observed plots of ΔS/S₀ (= 1 − S/S₀) values against the corresponding NcTr values forREDOR experiments of (AG)₆A[1-¹³C]G¹⁴AG[¹⁵N]A¹⁷G(AG)₆ to determine the distance between the [1-¹³C]Gly¹⁴ and [¹⁵N]Ala¹⁷ nuclei. Continuous and dotted lines show the theoretical dephasing curves corresponding to the designated distances. By comparing the REDOR data and the theoretical dephasing curve, the ¹³C-¹⁵N interatomic distance was determined to be 4.0 ± 0.1 Å. Reprinted with permission from ref. 21. Modified from ref. 21.
