# PPI: Protein-Protein Interfaces


## Overview

This task relates to predicting which pairs of amino acids, spanning two
different proteins, will interact upon binding (when they form a complex).

Amino acids are defined as interacting if any of their heavy atoms are within 6
Angstroms from one another.  


## Datasets
- splits:
   - DIPS-split: DIPS dataset, split by sequence identity (see add. inf.)


## Format

Each entry in the dataset contains the following keys:

- ['input_ids'] The set of atomic numbers for both the proteins in the complex concatenated together.
- ['coords'] The 3D coordinates for both the proteins in the complex concatenated together.
- ['label'] 1 for interacting, 0 for not interacting.
- ['token_type_ids'] A mask that corresponds to which inputs_ids/coords belong to the two individual proteins involved in the complex (0 for protein 1 , 1 for protein 2)


## Additional Information

The ensemble consists of a given protein complex, with subunits corresponding 
to the two individual proteins involved in the complex.
