(glycogen-synthase-D) phosphatase

Jump to: navigation, search

In enzymology, a [glycogen-synthase-D] phosphatase (EC is an enzyme that catalyzes the chemical reaction

[glycogen-synthase D] + H2O [glycogen-synthase I] + phosphate

Thus, the two substrates of this enzyme are [[[glycogen-synthase D]]] and H2O, whereas its two products are [[[glycogen-synthase I]]] and phosphate.

This enzyme belongs to the family of hydrolases, specifically those acting on phosphoric monoester bonds. The systematic name of this enzyme class is [UDP-glucose:glycogen 4-alpha-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_degree_C.
