Learn to Use Mol* for 3D Visualization
01/06
Mol* (molstar) is a modern, web-based open-source toolkit for visualization and analysis of large-scale molecular data. Mol* is used throughout RCSB.org, from generating the 2D images available for every structure and entity in the PDB; to offering interactive 3D views of structures, sequence annotations on structures, electron density; and close-up views of ligand interactions.
A standalone version of Mol* is also available that allows users to upload custom files and/or superimpose different structures in the same viewer.
To learn more about Mol* at RCSB.org:
- Introduction to Mol* Video Tutorial Series at PDB-101
- The supplementary material for the publication
Visualizing and Analyzing 3D Biomolecular Structures using Mol* at RCSB.org: Influenza A H5N1 Virus Proteome Case Study
(2025) Protein Science 34: e70093
provides instructions for recreating most of the Mol* visualizations from the main manuscript, along with additional details where needed. - Mol* tutorial playlist on YouTube, which includes some short demonstrations taken from the Protein Science publication
- Documentation at RCSB.org
