Glucose-6-phosphatase, catalytic subunit (glucose 6-phosphatase alpha) is an enzyme that in humans is encoded by the G6PC gene.[5][6]
Glucose-6-phosphatase is an integral membrane protein of the endoplasmic reticulum that catalyzes the hydrolysis of D-glucose 6-phosphate to D-glucose and orthophosphate. It is a key enzyme in glucose homeostasis, functioning in gluconeogenesis and glycogenolysis. Defects in the enzyme cause glycogen storage disease type I (von Gierke disease).[6]
