PDBx/mmCIF

PDBx/mmCIF is a digital format used to share detailed information about the 3D structures of biological molecules, like proteins and DNA. It organizes data about atomic positions, bonding, and other features in a standardized way, making it easier for scientists worldwide to access, analyze, and compare. This format builds upon an earlier system, making it more flexible and capable of handling complex structures, ensuring consistent and comprehensive data exchange in structural biology research.
