RCSB Protein Data Bank

The RCSB Protein Data Bank (PDB) is an online repository that stores detailed 3D structures of biological molecules such as proteins and DNA. These structures are determined through advanced techniques like X-ray crystallography and electron microscopy. Researchers worldwide use the PDB to study how molecules function, develop new medicines, and understand the basis of health and disease. It serves as a comprehensive, accessible resource for scientists to explore the intricate shapes of life's building blocks, promoting collaboration and innovation in biological and medical research.
