WebThis dissociation activates glycogen synthase and converts phosphorylase a to phosphorylase b. Phosphorylase b does not bind PP1 allowing PP1 to remain activated. When the muscles of the body signal for the need for glycogen degradation and increased glucose concentration, PP1 will be regulated accordingly. WebRecent work has demonstrated that phosphorylase kinase not only activates phosphorylase, but also phosphorylates glycogen synthase thereby decreasing its activity (45-49). The regulation of phosphorylase kinase by calcium ions may therefore also provide a mechanism for co-ordinating the rates of glycogenolysis and glycogen … university of pennsylvania mph programMuch research has been done on glycogen degradation through studying the structure and function of glycogen phosphorylase, the key regulatory enzyme of glycogen degradation. On the other hand, much less is known about the structure of glycogen synthase, the key regulatory enzyme of glycogen synthesis.
