Utility functions to work with KLIFS data

KLIFS

The klifs_utils package offers functions to interact with data from KLIFS (remotely and locally).

What is KLIFS and who created it?

Kinase-Ligand Interaction Fingerprints and Structures database (KLIFS), developed at the Division of Medicinal Chemistry - VU University Amsterdam, is a database that revolves around the protein structure of catalytic kinase domains and the way kinase inhibitors can interact with them

• KLIFS database: https://klifs.vu-compmedchem.nl
• KLIFS online service: https://klifs.vu-compmedchem.nl/swagger
• KLIFS citation
  • Description of the database itself (J. Med. Chem. (2014), 57, 2, 249-277)
  • Description of the online service (Nucleic Acids Res. (2016), 44, 6, D365–D371)

Installation

1. Download GitHub repo:

   git clone https://github.com/volkamerlab/klifs_utils.git

   The library lives now in this example path /path/to/klifs_utils.

2. Install and activate conda environment klifs_utils:

   cd /path/to/klifs_utils/devtools/conda_envs/
   conda env create -f env.yaml
   conda activate klifs_utils

3. Install library in conda environment while being in path /path/to:

   pip install klifs_utils

Alternative if you already have the klifs_utils environment installed:

pip install https://github.com/volkamerlab/klifs_utils/archive/master.tar.gz

Usage

Check out the klifs_utils tutorial (Jupyter notebook):

/klifs_utils/docs/tutorial.ipynb

Work with KLIFS data from KLIFS server (remotely)

The klifs_utils.remote module offers you to access KLIFS data from the KLIFS server.

This module uses the official KLIFS API: https://klifs.vu-compmedchem.nl/swagger.

Work with KLIFS data from disc (locally)

The klifs_utils.local module offers you to access KLIFS data from the KLIFS server. In order to make use of the module's functionality, you need a KLIFS download folder KLIFS_download with the following structure:

└── KLIFS_download
    ├── KLIFS_export.csv           # Metadata file
    ├── overview.csv               # Metadata file
    └── HUMAN     	               # Species name
        ├── AAK1                   # Kinase name
        │   ├── 4wsq_altA_chainA   # PDB ID, alternate model ID, chain ID
        │   │   ├── complex.mol2
        │   │   ├── ligand.mol2
        │   │   ├── protein.mol2
        │   │   ├── pocket.mol2
        │   │   └── water.mol2
        │   └── ...
        └── ...

Download KLIFS data from: https://klifs.vu-compmedchem.nl

Library structure

The libraries structure looks like this, trying have the same API for both modules local and remote (whenever possible):

├── local/
│   ├── coordinates/
│   │   ├── complex.py
│   │   ├── ligand.py
│   │   ├── protein.py
│   │   ├── pocket.py
│   │   └── water.py
│   ├── initialize.py
│   ├── interactions.py
│   ├── kinases.py
│   ├── ligands.py
│   └── structures.py
├── remote/
│   ├── coordinates/
│   │   ├── complex.py
│   │   ├── ligand.py
│   │   ├── protein.py
│   │   └── pocket.py
│   ├── interactions.py
│   ├── kinases.py
│   ├── ligands.py
│   └── structures.py
└── util.py

This structure mirrors the KLIFS Swagger API structure in the following way to access different kinds of information both remotely and locally:

• kinases (in KLIFS called information): Get information about kinases (groups, families, names)
• interactions: Get interaction fingerprint via structure_ID
• ligands: Get ligand information
• structures: Get structure information
• coordinates (in KLIFS part of structures): Get structural data (structure coordinates)

Note: In order to use the local module, it is necessary to initialize a metadata file (local.initialize module).
