Fig. 6From: Learning protein binding affinity using privileged informationNumber of interacting residue pairs (NIRP) in the interface of a protein complex. The frequency of non-repeating pairs (considering A: B and B: A the same) was computed from the bound 3D structures of ligand (L) and receptor (R) of a protein complex. Residues (shown as spheres) at a distance cutoff of 8Â Ã… are considered the interface of the complex. The bottom panel of the figure shows the form of the feature vector extracted using this schemeBack to article page
