LBA: Ligand Binding Affinity
Overview
In this task, we predict the binding affinity of ligands to their corresponding proteins based on the co-crystallized structure of the protein-ligand complex. We predict experimentally measured binding affinity as pK, defined as -log(Ki) or -log(Kd), depending on which measurement is available.
We derive crystal structures and ligand binding data from PDBBind (Wang et al., 2004), a widely-used curated database of protein-ligand complexes with experimental affinities derived from literature. We use the 2019 update of the so-called "refined set", a subset of complexes selected based on the quality of the structures and the affinity data. After filtering ligands which could not be read by RDKit due to invalid bonding data, our final dataset consists of 4,463 complexes.
Datasets
- splits:
- split-by-sequence-identity-30: No proteins with seq. id. of more than 30% are in the same set.
Format
Each entry in the dataset contains the following keys:
['input_ids'] The set of atomic numbers for the protein, pocket and ligand atoms concatenated together.
['coords'] The 3D coordinates for the protein, pocket and ligand atoms concatenated together.
['label'] experimentally measured binding affinity as pK.
['token_type_ids'] A mask that corresponds to which inputs_ids/coords belong to the protein, pocket or ligand atoms (0 for protein , 1 for pocket, 2 for ligand)
