The lock shapes the key
Date:2/15/2011

rements of the binding process of the altered peptide have now shown that the hydrogen bonds in the S-peptide, and as such in the α-helical structure, do not form until after the bonding to the S-protein. Thus, they cannot play a role in the recognition process. Protein-protein recognition in this case takes place via hydrophobic interaction of the S-protein with two spatially clearly defined areas of the unstructured S-peptide.

These results are of fundamental importance for understanding the mechanism of protein-protein interactions. In the future, this method can be used to examine in detail the structure formation in proteins in other systems, as well.
