Mol* is an open-source molecular visualization tool developed by RCSB PDB and PDBe for viewing 3D biomolecular structures. It aids research, education, and data dissemination by visualizing atomic coordinates and annotations from various sources.
Area of Science:
- Structural Biology
- Bioinformatics
- Computational Chemistry
Background:
- Visualizing three-dimensional (3D) biomolecular structures is crucial for understanding their function.
- Existing tools may have limitations in handling diverse biostructures and integrated data.
Purpose of the Study:
- Introduce Mol* as an open-source, web-based 3D visualization software suite.
- Demonstrate its capabilities in visualizing and analyzing biomolecular structures and associated data.
Main Methods:
- Collaborative development of Mol* by RCSB PDB and PDBe.
- Implementation of Mol* within the RCSB.org web portal for seamless visualization.
- Integration of atomic coordinates, experimental data, and bioinformatics annotations.
Main Results:
- Mol* facilitates single-mouse-click visualization of various biomolecules (proteins, nucleic acids, etc.) with ligands and ions.
- It enables seamless display, interrogation, superimposition, and comparison of 3D structures from diverse sources.
- Case study with influenza A H5N1 virus demonstrates integration of sequence/structure annotations and analysis of structure groups.
Conclusions:
- Mol* enhances research, training, and education by providing accessible 3D visualization of biostructures.
- It supports the examination of complex biomolecular assemblies and integrates diverse data resources.
- Standalone Mol* is available for visualizing any atomic-level or multi-scale biostructure.

Globular and Fibrous Proteins
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...
