The activation is dependent on the presence of AMP. Activation by fructose diphosphate and AMP, and inhibition by ATP, is primarily due to large changes in the apparent affinity of the enzyme for the substrate fructose 6-phosphate. These control properties can account for the generation of glycolytic oscillations. The enzyme was also studied under conditions approximating the metabolite contents of skeletal muscle in vivo (pH 7.0, 10mM ATP, 0.1 mM fructose 6-phosphate). Under these more inhibitory conditions, phosphofructokinase is strongly activated by low concentrations of fructose diphosphate, with half-maximal activation at about 10 muM. Citrate is a potent inhibitor at physiological concentrations, whereas AMP is a strong activator. Both AMP and citrate affect the maximum velocity and have little effect on affinity of the enzyme for fructose diphosphate."xsd:string |
