• Backbone structures are obtained using ProteinViewer, where N-terminal is colored red and C-terminal blue.
• Superposition of monomers and their Z-scores and superimposed RMSDs are computed by the DaliLite server.
• DSSP state sequences are obtained from the PDB database of the EMBL-EBI. When they are not available, the DSSPcont server is used.
• In the images, the CA atoms of D2 variable regions are drawn as large black (chain A) and white (chain B) sphere.
  
• Click the images to view larger image.
• See the bottom for brief explanation of the D2 codes and the DSSP states. 
• '+', '*', and '-' indicate the residues with different D2 codes/DSSP states, where '*' corresponds to visually indistinguishable differences, and '-' corresponds to very small structural differences.
