For example, ATP allosterically inhibits phosphofructokinase, but it activates the functionally opposite enzyme fructose-1,6-bisphosphatase (see slide 7.5.3). Similarly, phosphorylation inhibits glycogen synthase but activates glycogen phosphorylase, which degrades glycogen (slide 8.4.1).llosteric regulation of phosphofructokinase by AMP. To accomplish the stimulation of phosphofructokinase, AMP interacts with the enzyme at an allosteric binding site, that is, a site that is distant and functionally distinct from the active site.
Hexokinase is an enzyme that phosphorylates a six-carbon sugar, a hexose, to a hexose phosphate. In most tissues and organisms, glucose is the most important substrate of hexokinases, and glucose 6-phosphate the most important product.his produces glucose-6-phosphate still bound to hexokinase and ADP still in complex with magnesium ion [5]. Glucose-6-phosphate and the magnesium-ADP complex leave hexokinase. Glucose-6-phosphate and ADP are the products of this reaction.
