Popis: A comparison has been made of the kinetic parameters obtained with yeast hexokinase using Mg 2+ or Ni 2+ as metal ion activator and ATP or tubercidin-5′-triphosphate as nucleotide substrate. It is concluded that the relative specificity of the enzyme for MgATP 2− does not involve a contribution arising from an interaction of the metal ion with the purine ring of the nucleotide.
