2.7.3.1	the crystal structures of recombinant glycocyamine kinase alphabeta and glycocyamine kinase betabeta from Namalycastis sp. are determined at 2.6 A and 2.4 A resolution, respectively. In addition, the structure of the glycocyamine kinase betabeta is determined at 2.3 A resolution in complex with a transition state analog, Mg2+ ADP-NO3- glycocyamine. In both heterodimeric and homodimeric glycocyamine kinase forms, the conformations of the two N-termini are asymmetric and the asymmetry is different than that reported previously for the homodimeric creatinine kinases from several organisms	721618
