Figure 3From: Functional evolution of two subtly different (similar) foldsSuperposition of various OB (left) and SH3-fold (right) structures showing the structural conservation of strands and variations in the loops. The loops are labeled as in Figures 1 and 2. The orientation of the molecules is same as in Figure 1 and 2 for SH3-fold and OB-folds.Back to article page
