## What is PDB Viewer?

PDB Viewer turns your phone into a molecular microscope. Search the entire Protein Data Bank and over 200 million AlphaFold predictions, then explore any protein, virus, drug, or DNA structure in interactive 3D — free, with no account, no ads, and no sign-up.

WHERE THE MOLECULES COME FROM
• RCSB Protein Data Bank — 200,000+ experimentally determined structures
• AlphaFold — 200M+ AI-predicted protein models
• SWISS-MODEL — template-based homology models
• PubChem and ChEMBL — millions of drugs and compounds
• Crystallography Open Database — small-molecule crystals
• NCI/CADD resolver — type a chemical name and get a 3D model
Every source is free and needs no API key. You can also open your own .pdb and .cif files.

WAYS TO SEE IT
• Five representations: wireframe, ball-and-stick, space-filling (CPK), cartoon/ribbon, and a smooth molecular surface
• Color by element, chain, secondary structure, rainbow, or AlphaFold confidence (pLDDT)
• Biological assemblies: rebuild an entire icosahedral virus capsid from a few deposited chains
• NMR ensembles: overlay every model in the bundle to watch a protein flex
• Automatic secondary-structure detection

MADE FOR TOUCH
• Rotate, pinch-zoom, and pan with smooth native rendering
• Tap any atom to see its element, residue, and chain
• Recently viewed structures are cached, so they reopen instantly and work offline

For students, researchers, teachers, and the simply curious. PDB Viewer makes structural biology beautiful and accessible.

Structures are provided by their respective databases. PDB Viewer is independent and not affiliated with or endorsed by the RCSB PDB, EMBL-EBI, or AlphaFold.
