Figure 3
The Ci−1—Ni—Cαi angle before and after correction of X-Pro tc+ cases. The curved lines show Gaussian kernel density estimates for the Ci−1—Ni—Cαi backbone angle for 25 X-Pro tc+ cases in the test set before (solid line) and after (dashed line) correction and re-refinement. The vertical lines show the values for trans-Pro (119.3 ± 1.5°) and cis-Pro (127.0 ± 2.4°) reported by Engh & Huber (2001BB16).
