BFEE-Docking

Author: Haohao Fu (fhh2626@nankai.edu.cn, fhh2626@gmail.com)

Introduction

BFEE-Docking is an open-source companion platform to BFEE3 for automated structure-based drug discovery workflows. It integrates virtual screening, flexible redocking, MD preparation, MM-GBSA calculations, and BFEE3-based absolute binding free-energy calculations into a single graphical workflow.

Starting from a standard protein PDB file and a ligand database in SMI/SDF/MOL2 format, BFEE-Docking can automate many routine preparation steps, including protein cleaning, pH-dependent protonation-state assignment, ligand preprocessing, binding-site definition, docking/redocking, file-format conversion, and preparation of downstream MD or free-energy calculation files.

BFEE-Docking also interfaces with PyMOL, allowing users to visualize binding pockets, docking boxes, docked ligand conformations, and flexible residues during the workflow.

Main features:

Automated protein and ligand preprocessing
pH-dependent protonation-state handling
Binding-site definition by blind docking, pocket prediction, co-crystallized ligand, or manual input
Rigid docking and flexible redocking
Support for DSDP, smina, AutoDock Vina, QVina2, QVinaW and GNINA
PyMOL-based visualization of intermediate results
Preparation of MD-ready files for OpenMM simulations
Support for MM-GBSA calculations
Connection to BFEE3 for absolute binding free-energy calculations
