Protein

Glucose-6-phosphatase

Gene

G6PC

Organism
Canis familiaris (Dog) (Canis lupus familiaris)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Hydrolyzes glucose-6-phosphate to glucose in the endoplasmic reticulum. Forms with the glucose-6-phosphate transporter (SLC37A4/G6PT) the complex responsible for glucose production through glycogenolysis and gluconeogenesis. Hence, it is the key enzyme in homeostatic regulation of blood glucose levels (By similarity).By similarity

Catalytic activityi

D-glucose 6-phosphate + H2O = D-glucose + phosphate.
