Amide bridge interactions between amino acids Asn and Gln.
A) Interaction structure of amide bridge for the Asn-Asn interaction. B) Interaction structure of amide bridge for the Asn-Gln interaction. C) Interaction structure of amide bridge for the Gln-Gln interaction. The energies of aa amide bridge interactions are in the range -65 to -70 kJ/mol.
