Interaction

1、Solvent accessible surface areas (SASA) were calculated (Naccess V2.1.1) for each residue in antibody and antigen, respectively. The residues with SASA loss in binding of more than 1Å2 were classified as interacting residues.

Interacting residues (ΔSASA based)

2、We defined interacting paratope-epitope residues by a distance cutoff of < 5Å . Two amino acids are considered as interacting residues if they have at least one atom within a distance of 5 Å from any atom.

Interacting residues (Atom distance based)

Within the threshold, the structure has no interacting amino acids and cannot be displayed. This may be due to the following reasons:
1. The method used to determine the structure is electron microscopy or nuclear magnetic resonance, which results in too low resolution;
2. the coordinates of some amino acids involved in the interaction in the structure were not detected due to technical limitations. The results are less based on atomic coordinates, but the antibody does target the antigen.
