Protein-Ligand Interaction Fingerprints

:warning: This project is under development, do not use it in the current state :warning:

Description

ProLIF is a tool designed to generate Interaction FingerPrints (IFP) and compute similarity scores for protein-ligand interactions, given a reference ligand and a list of binding-site residues.

Installation

ProLIF is written in Python 3, and uses the following non-standard libraries:

To install rdkit with Anaconda, use the following command:

conda install -c rdkit rdkit

Usage

INPUT arguments:
  -r fileName, --reference fileName
                        Path to your reference ligand.
  -l fileName [fileName ...], --ligand fileName [fileName ...]
                        Path to your ligand(s).
  -p fileName, --protein fileName
                        Path to your protein.
  --residues RESIDUES [RESIDUES ...]
                        Residues chosen for the interactions. Default: automatically detect residues within --cutoff of the reference ligand
  --cutoff float        Cutoff for automatic residue detection. Default: 5.0 angströms
  --json fileName       Path to a custom parameters file. Default: prolif.json

OUTPUT arguments:
  -o filename, --output filename
                        Path to the output CSV file
  -v, --verbose         Increase terminal output verbosity

Other arguments:
  --interactions bit [bit ...]
                        List of interactions used to build the fingerprint.
                        -) hydrogen bond: HBdonor, HBacceptor
                        -) halogen bond:  XBdonor
                        -) ionic: cation, anion
                        -) pi-stacking: FaceToFace, FaceToEdge
                        -) hydrophobic
                        -) pi-cation
                        -) metal
                        Default: HBdonor HBacceptor cation anion FaceToFace FaceToEdge pi-cation hydrophobic
  --score {tanimoto,dice,tversky}
                        Similarity score between molecule A and B :
                        Let 'a' and 'b' be the number of bits activated in molecules A and B, and 'c' the number of activated bits in common.
                        -) tanimoto : c/(a+b-c). Used by default
                        -) dice     : 2c/(a+b)
                        -) tversky  : c/(alpha*(a-c)+beta*(b-c)+c)
  --alpha int           Alpha parameter for Tversky. Default: 0.7
  --beta int            Beta parameter for Tversky. Default: 0.3

Mandatory arguments: --reference --ligand --protein
