WebGlycogen phosphorylase causes phosphoroclastic cleavage into glycogen, and produces glycogen-1-phosphate. However, a non-reducing terminal is removed when cleaving glucose from glycogen. Moreover, if glucose-1-phosphate produced from glycogen is changed into G6P by phosphoglucomutase, it can proceed directly to glycolysis. Glycogen phosphorylase is one of the phosphorylase enzymes (EC 2.4.1.1). Glycogen phosphorylase catalyzes the rate-limiting step in glycogenolysis in animals by releasing glucose-1-phosphate from the terminal alpha-1,4-glycosidic bond. Glycogen phosphorylase is also studied as a model protein regulated by both reversible phosphorylation and allosteric effects.
