HADDOCK3 provides a powerful workflow to docke two or more protein structures and it provides multiple metrics as an output for quantifying molecular binding affinity. However, a full docking pipeline may take some time to complete.
To get binding affinity metrics for PDB files where the protein complex already exists, we don't necessarily need to perform a full docking workflow. Also, there is a need to understand binding affinity in protein complex files generated from multimer folding prediction tools like AlphaFold3, Boltz-1, or ESM3.
