About The Project

This method is based on geometric deep learning and is capable of predicting the binding conformations of ligands to protein targets. Concretely, the model learns a statistical potential based on distance likelihood which is tailor-made for each ligand-target pair. This potential can be coupled with global optimization algorithms to reproduce experimental binding conformations of ligands.

We showed that:

• Geometric deep learning can learn a potential based on distance likelihood for ligand-target interactions
• This potential performs similar or better than well-established scoring functions for docking and screening tasks
• It can be coupled with global optimization algorithms to reproduce experimental binding conformations of ligands

Getting Started

Prerequisites

This package runs using Pytorch and Pytorch Geometric. On top it uses standard packages such as pandas and numpy. For the complete list have a look into the requirements.txt file

• install requirements.txt

  pip install -r requirements.txt

• install RDKIT

  conda install -c conda-forge rdkit=2019.09.1

Installation

Using Dockerfile

To build image and run from scratch:

1. Install docker
2. Clone repo and move into project folder.

   git clone https://github.com/OptiMaL-PSE-Lab/DeepDock.git
   cd DeepDock

3. Build the docker image. This takes 20-30 mins to build

   docker build -t deepdock:latest .

4. Launch the container.

   docker run -it --rm --name deepdock-env deepdock:latest

From source

1. Clone the repo

   git clone https://github.com/OptiMaL-PSE-Lab/DeepDock.git

2. Move into the project folder and update submodules

   cd DeepDock
   git submodule update --init --recursive

3. Install prerequisite packages

   conda install -c conda-forge rdkit=2019.09.1
   pip install -r requirements.txt

4. Install DeepDock pacakge

   pip install -e .

Data

You can get training and testing data following the next steps.

1. Move into the project data folder

   cd DeepDock/data

2. Use the following line to download the preprocessed data used to train and test the model. This will download two files, one containing PDBbind (2.3 GB) used for training and another containing CASF-2016 (32 MB) used for testing. These two files are enough to run all examples.

   source get_deepdock_data.sh

3. In case you want to reproduce all results of the paper you will need to download the complete CASF-2016 set (~1.5 GB). You can do so with this command line from the data folder.

   source get_CASF_2016.sh

Usage

Usage examples can be seen directly in the jupyter notebooks included in the repo. We added examples for:

• Training the model
• Score molecules
• Predict binding conformation (docking)
