WebPhosphorylase b kinase (PhK) is a regulatory enzyme in the activation cascade of glycogenolysis. By phosphorylating and thus activating glycogen phosphorylase, PhK … WebThe change in shape modifies the protein’s function, thereby activating it. This provides the mechanism for “switching on” the signal transduction pathway. Alongside protein kinases, protein phosphatases are also present in the phosphorylation cascade.
