Protein Data Bank (PDB)

The Protein Data Bank (PDB) is an online database that stores detailed 3D structures of biological molecules like proteins and DNA. These structures are determined through scientific techniques such as X-ray crystallography or electron microscopy. By providing precise spatial information, the PDB helps researchers understand how these molecules function, interact, and contribute to living organisms. It is a vital resource for advancing biological and medical research, enabling scientists worldwide to access and analyze molecular models for drug development, biochemistry, and structural biology.
