FIGURE 3.

Comparison of helical and sheet content percent calculated using ¹H_α or ¹H_N ACS values to that obtained using a consensus chemical shift index-based method for a set of proteins for which no three-dimensional structures are available. (a) and (b) correspond to the helical content using the ¹H_α and ¹H_N ACS values, respectively, whereas (c) and (d) are the corresponding sheet content using the same ACS values. The dashed lines correspond to a perfect correlation between these two methods.
