Glucose 6-phosphatase-β is a ubiquitously expressed, 346-amino acid membrane protein that shares 36% sequence identity with glucose 6-phosphatase-α. Within the glucose 6-phosphatase-β enzyme, sequence alignments predict that its active site contains His167, His114, and Arg79.
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.
This gene encodes the catalytic subunit of glucose 6-phosphatase (G6Pase). G6Pase is located in the endoplasmic reticulum (ER) and catalyzes the hydrolysis of glucose 6-phosphate to glucose and phosphate in the last step of the gluconeogenic and glycogenolytic pathways. [5]
English: glucose-6-phosphatase system: in the end of the gluconeogenesis glc-6-p is transported into the ER (G6PT = T1) and dephosphorylated (G6Pase). Glucose is transported out of the cell passing two glucose-transporters (GLUT7 = T3 and GLUT2). Inorg. Phosphate is transported back to the cytosol by the T2 transporter
Glucose-6-phosphate exchanger SLC37A4, also known as glucose-6-phosphate translocase, is an enzyme that in humans is encoded by the SLC37A4 gene. [ 5 ] [ 6 ] [ 7 ] It consists of three subunits , each of which are vital components of the multi-enzyme Glucose-6-Phosphatase Complex (G6Pase).

Glycogen, which consists of branched long chains made out of the simple sugar glucose, is an energy storage form for carbohydrates in many human cells; this is most important in liver, muscle and certain brain cells. The monosaccharide glucose-6-phosphate (G-6-P) is typically the input substance for glycogenesis.
The G6P remains within the liver cell unless the phosphate is cleaved by glucose-6-phosphatase. This dephosphorylation reaction produces free glucose and free PO 4 anions. The free glucose molecules can be transported out of the liver cells into the blood to maintain an adequate supply of glucose to the brain and other organs. Glycogenolysis ...
