(glycogen-synthase-D) phosphatase

Class of enzymes

The enzyme [glycogen-synthase-D] phosphatase ({EC 3.1.3.42) catalyzes the reaction

[glycogen-synthase D] + H₂O ${\displaystyle \rightleftharpoons }$ [glycogen-synthase I] + phosphate

This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name is [UDP-glucose:glycogen 4-α-D-glucosyltransferase-D] phosphohydrolase. Other names in common use include uridine diphosphoglucose-glycogen glucosyltransferase phosphatase, UDP-glycogen glucosyltransferase phosphatase, UDPglucose-glycogen glucosyltransferase phosphatase, glycogen glucosyltransferase phosphatase, glycogen synthetase phosphatase, glycogen synthase phosphatase, glycogen synthase D phosphatase, Mg²⁺ dependent glycogen synthase phosphatase, and phosphatase type 2 °C.
