FEBS Lett., 439:133-137, 1998 Cited by PubMed Abstract: 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. PubMed: 9849893 DOI: 10.1016/S0014-5793(98)01355-6 PDB entries with the same primary citation
