AmberMDrun

AmberMDrun automates preparation, execution, and binding free energy calculation for molecular dynamics simulations using the AMBER suite to model biomacromolecules and receptor-ligand interactions.

Key Features:

• Automated Input Preparation: Automatically generates AMBER-compatible input files for MD simulations.
• System Balancing: Performs system balancing including charge neutralization and solvation to prepare stable biomolecular systems.
• Production Run Execution: Executes production molecular dynamics runs using the AMBER suite.
• Binding Free Energy Prediction: Predicts receptor-ligand binding free energies to quantify thermodynamics of molecular interactions.
• Extensibility and Integration: Supports customization and integration with other computational workflows.
• Implementation: Core implemented in C++ with Python bindings for scripting and integration.

Scientific Applications:

• Structural Biology: Supports simulation-based studies of protein structure and conformational changes.
• Biochemistry: Enables investigation of enzyme mechanisms and biomacromolecular dynamics.
• Pharmacology and Drug Design: Aids rational drug design through binding free energy calculations of receptor-ligand complexes.

Methodology:

Automated steps generate AMBER input files, perform system neutralization and solvation, run production MD using AMBER force fields, and produce binding free energy predictions using computational free-energy techniques.
