glycogen(starch) synthase EC#: 2.4.1.11; ChemWhat Code: 1377245
| Product Name | glycogen(starch) synthase |
| Example Structure | ![]() |
| Synonyms | Cg-GYS, GBSS, glucosyltransferase, uridine diphosphoglucose-glycogen, glycogen synthase, glycogen synthase 2, glycogen synthase-2, glycogen synthetase (starch), granule-bound starch synthase, GSN, GSY2p, Gys-2, GYS1, GYS2, Gys2p, UDP-glucose-glycogen glucosyltransferase, UDP-glycogen synthase, UDPG-glycogen synthetase, UDPG-glycogen transglucosylase, uridine diphosphoglucose-glycogen glucosyltransferase |
| EC Number | 2.4.1.11 |
| CAS Registry Number | 9014-56-6 |
| Comments | The accepted name varies according to the source of the enzyme and the nature of its synthetic product (cf. EC 2.4.1.1, phosphorylase). Glycogen synthase from animal tissues is a complex of a catalytic subunit and the protein glycogenin. The enzyme requires glucosylated glycogenin as a primer; this is the reaction product of EC 2.4.1.186 (glycogenin glucosyltransferase). A similar enzyme utilizes ADP-glucose (EC 2.4.1.21, starch synthase). |
