Integrative/Hybrid Methods Structural Biology: Role of Macromolecular Crystallography

Macromolecular crystallography has been central to the emergence and development of structural biology as a scientific discipline. Approximately 90% of the more than 138,000 three-dimensional structures currently available in the Protein Data Bank (PDB) archive, the single, global open access data resource for macromolecular structure data, were determined using X-ray crystallography. MX, the enormous variety of PDB structures of proteins, DNA, and RNA, and computational models derived therefrom will be central to the growth of integrative or hybrid (I/H) methods structural studies of macromolecular assemblies and other complex biological systems.
