• PubMed Abstract: 
  

  Creatine kinase (CK) catalyses the reversible transfer of the phosphate moiety from phosphocreatine (PCr) to ADP, generating creatine and ATP. The crystal structure of a cytosolic brain-type creatine kinase is reported at 2.3 A. The biological dimer sits on a crystallographic twofold axis. The N-terminal residues of both subunits come very close to the crystallographic twofold at the dimer interface. The electron density observed is consistent with two alternative conformations for the N-termini, as previously found for chicken brain-type creatine kinase.
