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.

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.
