Mol* (/'molstar/) is a modern web-based open-source toolkit for visualisation and analysis of large-scale molecular data
 
Open Mol* Viewer Viewer Documentation Issues & Feedback
High-performance graphics and data handling of the Mol* Viewer allow users to simultaneously visualise up to hundreds of (superimposed) protein structures, play molecular dynamics trajectories, render cell-level models at atomic detail with tens of millions of atoms, or display huge models obtained by I/HM such as the Nuclear Pore Complex.

The Mol* toolkit is a comprehensive solution for molecular data delivery, visualization and analysis that can be embedded into a wide range of 3rd party solutions. It includes a customizable plugin for high quality WebGL based molecular data visualization, as well as servers for model and experimental (X-ray, Cryo-EM, etc.) data delivery, efficient BinaryCIF data format support, and other exciting features.
PDBe
PDBe
EMBL-EBI provides an open source integration of Mol* used by data resources such as PDBe, PDBe-KB and AlphaFold DB. This implementation can be embedded as a JS plugin or a Web Component with helper methods to facilitate programmatic interactions between the web application and the 3D viewer. Its features include a superposition view for overlaying all observed ligand molecules on representative protein conformations.
RCSB PDB provides an open source integration of Mol* that implements additional functionality, including presets for the visualization of structure alignments and structure motifs such as ligand binding sites, or the option to interactively add or hide chains and other structural components as showcased by the 3D Protein Feature View.
