The RCSB, or Research Collaboratory for Structural Bioinformatics, is a prominent organization that focuses on the collection and dissemination of structural data related to biological macromolecules. It operates the Protein Data Bank (PDB), which is a critical resource for researchers studying the three-dimensional structures of proteins, nucleic acids, and complex assemblies. The RCSB provides tools and resources for scientists to analyze and visualize structural data. By offering educational materials and user-friendly interfaces, it supports advancements in fields such as biochemistry, molecular biology, and drug design, facilitating a deeper understanding of biological processes and the development of new therapies.
