Enzyme Information

2.4.1.11
Glycogen(starch) synthase.
based on mapping to UniProt P27472
UDP-alpha-D-glucose + ((1->4)-alpha-D-glucosyl)(n) = UDP + ((1->4)-alpha- D-glucosyl)(n+1).
-!- The description (official name) varies according to the source of the enzyme and the nature of its synthetic product. -!- 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. -!- A similar enzyme utilizes ADP-glucose (cf. EC 2.4.1.21).
