ProtSqueeze: simple and effective automated tool for setting up membrane protein simulations

Area of Science:

• Computational Biology
• Biophysics
• Molecular Modeling

Background:

• Setting up membrane protein simulations requires embedding proteins into lipid bilayers, a challenging step.
• Existing methods for lipid packing around proteins have significant drawbacks, limiting their practical use.

Purpose of the Study:

• To address the limitations of current techniques for protein insertion into lipid bilayers.
• To introduce ProtSqueeze, a novel software for automated and efficient protein-lipid bilayer embedding.

Main Methods:

• Analysis of existing protein insertion techniques for molecular dynamics simulations.
• Development and implementation of the ProtSqueeze software with a novel insertion algorithm.
• Demonstration of ProtSqueeze functionality through case studies.

Main Results:

• ProtSqueeze offers a simple, controllable, and automated protein insertion procedure.
• The software is platform-independent and compatible with various simulation packages without source code modification.
• ProtSqueeze is freely available under a general public license.

Conclusions:

• ProtSqueeze provides a significant improvement for setting up membrane protein simulations.
• The software lowers the barrier for researchers to perform complex molecular simulations.
• ProtSqueeze facilitates more accessible and efficient computational studies of membrane proteins.
