PDBsum: Structural summaries of PDB entries

Area of Science:

• Structural Biology
• Bioinformatics
• Computational Chemistry

Background:

• The Protein Data Bank (PDB) is a crucial repository for macromolecular structure data.
• Accessing and interpreting complex structural information from the PDB can be challenging for researchers.
• There is a need for user-friendly tools that provide comprehensive analyses of PDB entries.

Purpose of the Study:

• To introduce PDBsum, a web server designed to offer detailed structural information and analyses for PDB entries.
• To provide researchers with an accessible platform for visualizing and understanding protein structures and their interactions.
• To enable users to upload and analyze their own PDB files.

Main Methods:

• Web server development utilizing image-based analyses.
• Integration of tools for protein secondary structure identification.
• Inclusion of analyses for protein-ligand and protein-DNA interactions.
• Incorporation of structural quality assessment using PROCHECK.
• Interactive 3D structure visualization using RasMol, PyMOL, and 3Dmol.js.

Main Results:

• PDBsum offers a wide array of structural analyses, including secondary structure, interaction data, and quality assessments.
• Interactive 3D visualization tools allow for dynamic exploration of protein structures.
• Users can upload custom PDB files for personalized, password-protected analyses.
• The server provides freely accessible structural information for numerous PDB entries.

Conclusions:

• PDBsum serves as a valuable resource for structural biologists and researchers by simplifying the interpretation of PDB data.
• The web server enhances the accessibility and utility of macromolecular structural information.
• PDBsum facilitates a deeper understanding of protein structure-function relationships through comprehensive analyses and visualization.
