Mechanism and Regulation of Phosphofructokinase. Phosphofructokinase binds both Mg2+-ATP and fructose-6-phosphate (F6P) to make fructose-1,6-bisphosphate and Mg2+-ADP. Although the image with both of these products has not been determined, bound to the enzyme has been. There are three ligand binding sites per subunit.
The increased glucose does all of the following EXDCEPT. 1  Binds to phosphorylase a at an allosteric site and changes its conformation. 2  Inhibits both glycogen phosphorylase and glycogen synthase. 3  Causes a change in conformation of phosphorylase a that is a better substrate for protein phosphatase.
