Figure 5From: Computational survey of peptides derived from disulphide-bonded protein loops that may serve as mediators of protein-protein interactionsDistribution of the differences between average disulphide-bonded loop conservation scores and the average conservation scores of residues located immediately outside the disulphide-bonded loop. Positive values indicate disulphide-bonded loops more conserved than the regions surrounding them. The black distribution represents all SwissProt annotated disulphide-bonded loops, the red distribution represents disulphide-bonded loops on a PDB protein model surface, and the blue distribution seen at the base of the red distribution represents disulphide-bonded loops at a PDB interface. The green ’X’s underneath the histogram represent the conservation difference of the disulphide-bonded loops in Table 1 comprising over 50% of a PDB interface.Back to article page
