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.
It is the binding to other cells that stimulates the cells to cause inflammation. Montelukast works in a manner similar to zafirlukast (Accolate), blocking the binding of some leukotrienes to the cells that cause inflammation. Unlike zafirlukast, montelukast does not inhibit CYP2C9 or CYP3A4, two enzymes in the liver that are important in breaking down and eliminating many drugs.
