WebPhosphorylase b kinase plays an important role in providing energy for cells. The main source of cellular energy is a simple sugar called glucose. Glucose is stored in muscle and liver cells in a form called glycogen. Glycogen can be broken down rapidly when glucose is needed, for instance during exercise. WebPhosphorylases are a special group of non-Leloir-type glycosyltransferases that catalyze the phosphorylysis of the glycosidic bond at the nonreducing end, releasing a sugar 1-phosphate residue.10 Since the reaction is reversible, these enzymes are also used to carry out the glycosylation reaction using sugar-1-phosphate as the donor.
