Allosteric activation of brain hexokinase by magnesium ions and by magnesium-ion–adenosine triphosphate complex

1. Substrate-saturation curves of brain hexokinase for MgATP(2−) were sigmoidal at sub-saturating concentrations of glucose when the Mg(2+)/ATP ratio was maintained at 1:1. Under identical conditions, except that Mg(2+) was present in excess, hyperbolic curves were observed. 2. The number of binding...
