mmCIF (Macromolecular Crystallographic Information File) is a text-based data format developed by the International Union of Crystallography (IUCr) for representing crystallographic information, particularly for macromolecular structures like proteins and nucleic acids. It extends the CIF (Crystallographic Information File) format with a richer dictionary for structural biology data. mmCIF is widely used in the Protein Data Bank (PDB) for storing and exchanging 3D structural data.
