All the hydrogen bonds and the salt bridges between DQA/DQB chains and the peptide in both structures.

Columns ‘Molecule 1’/‘Residue’ 1 list the α or β chain of each DQ complex (column ‘Molecule 1’) and the residues that interact with the peptide (column Residue 1). Column ‘Molecule 2’ refers always to the peptide. In column ‘Residue 2’ the peptide’s residues that form H-bonds and salt bridges with any DQ-complex amino acid are listed. The atoms involved are shown.
