Graphical presentation of the NOEs observed for (A) 4 mM DD K in TFE/water 50:50 v/v, and (B) 1 mM DD K in 400 mM DPCd38/H2O and 5% D2O, pH 6. The dNN, dαN, and dβN are sequential NOEs, where strong and weak crosspeaks are indicated by thick and thin lines, respectively. The dαN (i, i + 3), dαβ(i, i + 3), and dαN (i, i + 4) medium-size connectivities link atoms of residues spaced as indicated by the horizontal lines. The outlines of the helical conformation are also indicated.
