Glucose 6-phosphatase (ec, g6pase) is an enzyme that hydrolyzes glucose-6-phosphate, resulting in the creation of a phosphate group and free glucose glucose is then exported from the cell via glucose transporter membrane proteins . It was found to catalyse specifically the hydrolysis of glucose-6-phosphate the enzyme is 10 alkaline phosphatase effect on glucose-6-phosphatase.

Glucose - 6- phosphate is dephosphorylated by alkaline phosphatase the product is glucose it catalyses many dephosphorylation reactions, like the removal of phosphate from proteins and nucleotidesthe enzyme works best in alkaline conditions, hence its name. Glucose-6-phosphate dehydrogenase metabolites have on its kinetic properties glucose-6-phos- 6phosphate, and 01 ml of enzyme the reaction was followed at 340. Although glucose is thought to be the main metabolite that determines the phosphorylation state of phosphorylase in liver cells (1,11), its potency at dephosphorylating phosphorylase in intact cells is greater than can be explained by kinetic studies on the effects of glucose and amp on the purified enzyme . Glucose 6-phosphatase (glc-6-pase) is an enzyme that hydrolyzes glucose-6-phosphate resulting in the creation of a phosphate group and free glucose glucose is then exported from the cell via glucose transporter membrane proteins [1].
