Metadynamics to Enhance Sampling in Biomolecular Simulations.

Area of Science:

• Computational Biology
• Biophysics
• Biochemistry

Background:

• Molecular dynamics (MD) simulations provide atomic-level detail for biological processes.
• Significant time scale differences exist between MD simulations and biological events.
• Enhanced sampling methods are crucial for overcoming these time scale limitations.

Purpose of the Study:

• To focus on the metadynamics family of enhanced sampling methods.
• To introduce metadynamics and its recent variants for biomolecular studies.
• To guide new users in selecting appropriate metadynamics parameters.

Main Methods:

• Metadynamics utilizes a history-dependent bias potential.
• The bias is based on one or more collective variables (slow degrees of freedom).
• Recent variants and frontier areas of metadynamics are discussed.

Main Results:

• The chapter provides an introduction to metadynamics and its applications.
• It details recent advancements in metadynamics for biomolecular simulations.
• Guidance is offered on parameter selection and application for new users.

Conclusions:

• Metadynamics is a powerful enhanced sampling technique for molecular dynamics.
• Understanding collective variables and parameter choice is key to successful application.
• The method facilitates the study of slow biological processes.
