Glycogen synthase heme
Did you know?
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.

WebADP-glucose is converted into linear α-1.4-glucose by glycogen synthase (GlgA) for the extending chain. The linear oligosaccharide is then converted into a highly branched structure by 1,4-alpha-glucan branching enzyme (GlgB). Two enzymes, i.e., glycogen phosphorylase (GlgP) and amylopullulanase (Amy), are involved in the catabolism of … WebNov 2, 2024 · Glycogen synthase is the regulatory enzyme for the pathway and is responsible for linking glycosyl residues in a 1,4 linkage. The reaction typically occurs on existing glycogen stores; however, in the absence of any stored glycogen the reaction …
