The crystal structure of human muscle creatine kinase has been determined by the molecular‐replacement method and refined at 3.5 Å resolution. The structures of both the monomer and the dimer closely resemble those of the other known structures in the creatine kinase family. Two types of dimers, one with a non‐crystallographic twofold symmetry axis and the other with a crystallographic twofold symmetry axis, were found to occur simultaneously in the crystal. These dimers form an infinite `double‐helix'‐like structure along an unusual long crystallographic 3 1 axis.
