2c1A

2C1A is a four-character alphanumeric accession code used by the Protein Data Bank (PDB) to identify a specific deposited macromolecular structure. In practice, PDB codes are uppercase letters and digits, and the capitalization is significant for database lookup. The code itself is an arbitrary identifier assigned at the time of data deposition and does not convey structural details about the molecule.

An entry associated with a PDB code typically contains metadata about the structure, including the proposed title, the authors responsible for the deposition, and the biological source of the macromolecule. It also lists the macromolecular components present in the structure (such as proteins, nucleic acids, and bound ligands), as well as experimental details such as the determination method (for example X-ray crystallography, nuclear magnetic resonance, or cryo-electron microscopy) and the reported resolution or other quality metrics. Additional information may cover the crystallization conditions, symmetry, chain identifiers, and validation reports.

Accessing details for 2C1A involves searching reputable PDB portals such as the RCSB PDB or PDBe. These databases provide the structure’s 3D viewer, downloadable coordinates, associated literature, and cross-references to related biological data. If a direct match for 2C1A is not found, users should verify the code’s capitalization and consider verifying the entry in official deposition records, since PDB IDs are unique and case-sensitive.
