The Research Collaboratory for Structural Bioinformatics (RCSB) is a collaborative initiative that focuses on the study of biological macromolecules. It provides access to a wealth of structural data, primarily through the Protein Data Bank (PDB), which houses three-dimensional structures of proteins, nucleic acids, and complex assemblies. This resource is essential for researchers in fields such as biochemistry, molecular biology, and drug design. RCSB aims to enhance the understanding of molecular structures and their functions by offering tools and services for data analysis and visualization. It supports scientific research by facilitating collaboration among scientists and providing educational resources to promote the use of structural data in various applications.
