PDB (Protein Data Bank)

The Protein Data Bank (PDB) is an online database that stores detailed 3D structures of biological molecules, mainly proteins and nucleic acids. These structures are determined through experimental techniques like X-ray crystallography or cryo-electron microscopy. Scientists worldwide use the PDB to study how these molecules function and interact, which is essential for understanding health, disease, and developing medicines. Think of the PDB as a comprehensive library of molecular blueprints that helps researchers visualize the intricate architecture of life's building blocks.
