    The crystal structure of rabbit muscle creatine kinase, solved at 2.35 A resolution by X-ray diffraction methods, clearly identified the active site with bound sulfates surrounded by a constellation of arginine residues. The putative binding site of creatine, which is occupied by a sulfate group in this analysis, has been tentatively identified. The dimeric interface of the enzyme is held together by a small number of hydrogen bonds.
