Glycogen synthase

An enzyme of the transferase class that catalyses the reaction of udpglucose and (1,4-alpha-d-glucosyl)n to yield udp and 1,4-alpha-d-glucosyl)n+1. The reaction is highly regulated by allosteric effectors, by phosphorylation reactions, and by insulin.

Chemical name: UDPglucose:glycogen 4-alpha-D-glucosyltransferase
