Glycogen storage disease type 0 is a disease characterized by a deficiency in the glycogen synthase enzyme (GSY). Although glycogen synthase deficiency does not result in storage of extra glycogen in the liver, it is often classified as a glycogen storage disease because it is another defect of glycogen storage and can cause similar problems.

2020-07-06 · Glycogen synthase This is the key enzyme for glycogen synthesis. It catalyzes the transfer of glucose units from UDP-G to glycogen primer (an already existing chain of glucose molecules) so that C 1 of activated glucose of UDP-G is linked to C 4 of the terminal glucose unit in the glucogen primer (growing glycogen) by α 1, 4 glucosidic linkages.

Glycogen synthase catalyzes the rate-limiting step of glycogen biosynthesis and has two major isoforms in mammals -- muscle isoform (GYS1) and liver isoform (GYS2) respectively (1). Glycogen synthase kinase-3α (GSK-3α) and glycogen synthase kinase-3β (GSK-3β) phosphorylate glycogen synthase at multiple sites in its C-terminus (Ser641, Ser645, Ser649 and Ser653) inhibiting its activity (2, 3).

2021-01-28 Muscle glycogen synthase (M.W. ∼340,000) is a tetramer of identical subunits that exists in several forms, which differ in catalytic activity and degree of covalent modification.

Despite intensive research, the exact mechanisms that trigger AD are still not known and at the present there is no cure for it. In recent years, many signaling pathways associated with AD neuropathology have been explored as possible candidate targets for the treatment of this condition including glycogen synthase kinase-3β (GSK3-β). Search results for glycogen synthase at Sigma-Aldrich.

Furthermore, glycogen synthase can only add glucoses with an α(1->4) link. For branching to occur, a branching enzyme (specifically, amylo-(1,4->1,6)-transglycosylase is needed. This enzyme can transfer terminal chain segments to the 6-carbon hydroxyl of any glucose in a glycogen chain.

The glycogen content of tissues depends on the activity ratio of phosphorylase and glycogen synthetase, as well as on the tissue’s glucose supply from the blood. Lowering the blood sugar leads to a high phosphorylase activity, and so-called glycogen mobilization takes place, accompanied by its disappearance from the cytoplasm. The protein encoded by this gene, liver glycogen synthase, catalyzes the rate-limiting step in the synthesis of glycogen - the transfer of a glucose molecule from UDP-glucose to a terminal branch of the glycogen molecule. Mutations in this gene cause glycogen storage disease type 0 (GSD-0) - a rare type of early childhood fasting hypoglycemia with decreased liver glycogen content.

Activators of glycogen synthase. PP1 works on glycogen synthase as well as glycogen phosphorylase. By dephosphorylates glycogen synthase, PP1 activates it. PP1 is, in turn, activated by factors shown on the illustration to the right. PP1 is therefore the only regulator that directly regulates both glycogen synthase and glycogen phosphorylase.
