Glycogen synthase (UDP-glucose-glycogen glucosyltransferase) is a key enzyme in glycogenesis, the conversion of glucose into glycogen. It is a glycosyltransferase (EC 2.4.1.11) that catalyses the reaction of UDP-glucose and (1,4-α-D-glucosyl) n to yield UDP and (1,4-α-D-glucosyl) n+1

It is a glycosyltransferase that catalyses the reaction of UDP-glucose and n to yield UDP and n+1. Glycogen synthase, as discussed earlier, catalyzes the rate-limiting step in glycogen synthesis in the liver and in skeletal muscle, namely, the transfer of glucose monomers from UDP-glucose to the terminal branch of the growing glycogen chain via the formation of α(1→4) glycosidic bonds. 79 Several glycogen synthase isoforms exist – one specific to skeletal muscle (encoded by GYS1), and one specific to the liver (encoded by GYS2).
