1CD6

1CD6 is a four-character alphanumeric identifier used by the Protein Data Bank (PDB) to catalogue a specific macromolecular structure. PDB IDs are assigned to entries that store atomic coordinates derived from experiments such as X-ray crystallography, nuclear magnetic resonance spectroscopy, or cryo-electron microscopy, along with experimental details and metadata.

Each entry typically includes the deposited coordinates, the method used to determine the structure, resolution estimates, quality metrics (such as R-work and R-free in crystallography), and bibliographic information with authors and publication. The entry also lists the biological macromolecule, organism source when known, chain identifiers, and any ligands, cofactors, or metal ions present in the structure.

1CD6 can be accessed through the Protein Data Bank’s websites (for example, RCSB PDB) and mirrored databases like PDBe or PDBj. The page for 1CD6 provides the 3D coordinates, validation reports, downloadable files for coordinates and structure factors, and links to related literature. Researchers use such entries for structural analysis, visualization, and comparative studies, and the record may be updated if new information or corrections become available.

In summary, 1CD6 serves as a stable reference point within structural biology for retrieving a specific macromolecular structure and its associated data.
