FIGURE 2.

The cumulative properties of the bridging themes in our data set. (a) Length distribution around the average of 53 residues (restricted to more than 20 residues by design). (b) Distribution of RMSD between the Cα‐s of aligned residues in the two variants of the shared theme, after optimal superpositioning. The RMSD was calculated for the 469 pairs with all residues found in the PDB files. The average RMSD is 12.2 Å. (c) Distribution of sequence identity (in blue, averaging 36.7%) and similarity (in orange, averaging 70.3%) among aligned residues in the two variants of the shared themes
