Figure 4

Structural superposition of the two preserved segments in two unrelated proteins with different folds. (A) Two β-hairpin-like segments of FLVC-segment (green) and BPTI-segment (blue) are superimposed (2.49Å Cα RMSD). (B) Different structures of 1jnrA (left) and 1kthA (right) are shown. The corresponding portion (yellow) of the two segments forms a β-hairpin-like structure in both proteins.
