The macromolecular Crystallographic Information File (mmCIF) format is an extensible standard for the representation of macromolecular structures, including proteins and nucleic acids. Developed by the Worldwide Protein Data Bank (wwPDB), mmCIF addresses the limitations of the traditional PDB ormat by offering greater flexibility and capacity for complex data. It supports comprehensive metadata, including atomic coordinates, experimental data, and annotations. The format is structured in a tabular manner, making it highly compatible with modern database and data management systems. The mmCIF format facilitates the efficient storage, exchange, and processing of large and intricate datasets, ensuring robust and detailed representations of macromolecular structures.

For more information, pleasen refer to the official mmCIF format documentation.
