The Protein Data Bank

The Protein Data Bank (PDB) is an online repository that stores detailed 3D structures of proteins, DNA, and other biological molecules. These structures reveal how molecules are shaped and arranged, helping scientists understand their function and interactions. Researchers worldwide submit their structural data to the PDB, which then makes this information freely accessible for scientific study, drug development, and education. Essentially, the PDB acts as a global database that visually and structurally catalogs the building blocks of living organisms, advancing our knowledge of biology and medicine.
