Glycogen synthase

Glycogen synthase is an enzyme of the transferase class that catalyses the reaction of UDP-glucose and (1,4- &alpha; -D-glucosyl)n to yield UDP and (1,4- &alpha; -D-glucosyl)n+1. In other words, this enzyme binds excess glucose residues one by one into a chain for storage in glycogen. The reaction is highly regulated by allosteric effectors, by phosphorylation reactions, and indirectly triggered by insulin.

Chemical name: UDP-glucose-glycogen glucosyltransferase
