Our team performed MUSTANG server alignment test to see whether there is significant difference of 3D structure between DiphTox (DT) and original diphtheria toxin. The result of RMSD (Root Mean Square Deviation) between DT and original toxin is 0.969 Å. For the result of RMSD is below the value of 2 Å, it means there is no significant structural difference between these two molecules. <br>

Design Notes

Our team performed MUSTANG server alignment test to see whether there is significant difference of 3D structure between DiphTox (DT) and original diphtheria toxin. The result of RMSD (Root Mean Square Deviation) between DT and original toxin is 0.969 Å. For the result of RMSD is below the value of 2 Å, it means there is no significant structural difference between these two molecules.

Characterization or purification of those proteins would promote the usage of His-tag; therefore, insertion of His-tag inside the sequence is essential. To ensure the slightest change of tertiary structures of each protein, we would need to find out the secondary structure and surface accesibility via NetSurfP analyser version 1.1 (http://www.cbs.dtu.dk/services/NetSurfP/). We would insert His-tag sequence in either no available specific protein domain or the coiled secondary structure of protein to minimize any interruptions. Table 1 shows DT data from NetSurfP server.
