SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill helps researchers set up, run, and interpret molecular dynamics simulations without manually stitching together multiple tools and analysis steps.

Core Features & Use Cases

  • System Preparation: Build solvated biomolecular systems, assign force fields, and fix common structure issues before simulation.
  • Simulation Workflow: Perform energy minimization, NVT equilibration, NPT production, and checkpointed runs with OpenMM.
  • Trajectory Analysis: Measure structural behavior with RMSD, RMSF, contacts, secondary structure, principal components, and free energy surfaces using MDAnalysis.
  • Use Case: A structural biologist can prepare a protein-ligand complex, run a short production trajectory, and compare binding-induced flexibility across residues.

Quick Start

Ask the molecular-dynamics skill to prepare your structure, run equilibration and production, and analyze the trajectory for RMSD, RMSF, and protein-ligand contacts.

FAQPage Schema
How do I run molecular dynamics simulations and trajectory analysis for a protein-ligand complex?

You can set up and analyze molecular dynamics simulations by building a solvated biomolecular system, assigning force fields, and running energy minimization, equilibration, and production. Trajectory analysis provides RMSD, RMSF, and protein-ligand contact metrics via MDAnalysis.

What structural metrics can I calculate from an MD trajectory using MDAnalysis?

From an MD trajectory, MDAnalysis calculates structural metrics such as RMSD, RMSF, contacts, secondary structure, principal components, and free energy surfaces to quantify conformational changes and binding-induced flexibility.

Can I use OpenMM and PDBFixer to prepare solvated biomolecular systems for molecular dynamics?

OpenMM and PDBFixer support biomolecular system preparation for molecular dynamics by fixing common structure issues, building solvated systems, and assigning force fields for proteins, ligands, membranes, and nucleic acids.

Does this molecular dynamics workflow support membrane, nucleic-acid, and disordered-protein simulations?

The molecular dynamics workflow supports protein, ligand, membrane, nucleic-acid, and disordered-protein simulations, covering system setup, force-field assignment, periodic boundary conditions, energy minimization, equilibration, and production runs.

What is the best way to compare binding-induced flexibility across residues in a protein simulation?

To compare binding-induced flexibility, run a production trajectory and analyze it for RMSF and protein-ligand contacts. This trajectory analysis quantifies residue-level structural behavior and flexibility changes upon binding.
