Confusion between SCOP folds of class B. Color scheme is the same as in Figure 4. Domain (a) d1tvda_ and domain (b) d1pama1 belong to the same fold, b.1 (sandwich; 7 strands in 2 sheets; greek-key), and are found similar with Pcli = 3 and Zscor e = 3.38. Domain (c) d1ep3b1 and domain (d) d1d2ea1 belong to the same fold, b.43 (barrel, closed; n = 6, S = 10; greek-key), and are found similar with Pcli = 4.5 and Zscore = 3.7. Domains (b) and (c) belong to folds defined by different folding patterns. Both VAST and SHEBA found them similar with Pcli = 3.1 and Zscore = 3.32. Domains (a) and (d) were found dissimilar by VAST and SHEBA with a Pcli = -1.8, and a Zscore = 0.73.
