WebJun 1, 2002 · Abstract. The Protein Data Bank (PDB) is the single worldwide repository of structural data of biological macromolecules. This paper describes the goals of the PDB, the systems in place for data deposition and access, how to obtain further information, and near-term plans for the future development of the resource. X-ray crystallography is the primary method for determining the molecular conformations of biological macromolecules, particularly protein and nucleic acids such as DNA and RNA. In fact, the double-helical structure of DNA was deduced from crystallographic data. The first crystal structure of a macromolecule was solved in 1958, a three-dimensional model of the myoglobin molecule obtained by X-ray analysis. The Protein Data Bank (PDB) is a freely accessible repository for th… WebMay 31, 2013 · The elucidation of the three dimensional structure of biological macromolecules has provided an important contribution to our current understanding of … data structures used in git
