Figure 2.

Sequential and medium-range NOEs used to verify the secondary structure elements derived from CSI analysis. NOEs between amide protons of consecutive residues and between H^α and the amide proton of subsequent residues are represented by bars connecting the residues. For NN(i, i+1) and αN(i, i+1) NOEs, the thickness of the bar qualitatively represents the relative intensity (weak, medium, or strong) of the NOE. The NOEs for four octarepeats are not shown because they were assigned only to residue types in the repeat region because of overlap. The three unambiguously identified α-helices also are shown.
