Glucosylglycerol 3-phosphatase

From Wikipedia, the free encyclopedia

In enzymology, a glucosylglycerol 3-phosphatase (EC 3.1.3.69) is an enzyme that catalyzes the chemical reaction

2-(beta-D-glucosyl)-sn-glycerol-3-phosphate + H₂O $\rightleftharpoons$ 2-(beta-D-glucosyl)-sn-glycerol + phosphate

Thus, the two substrates of this enzyme are 2-(beta-D-glucosyl)-sn-glycerol-3-phosphate and H₂O, whereas its two products are 2-(beta-D-glucosyl)-sn-glycerol 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 2-(beta-D-glucosyl)-sn-glycerol-3-phosphate phosphohydrolase. This enzyme is also called salt tolerance protein A, StpA.
