Protein

Glucose-6-phosphatase

Gene

G6PC

Organism
Canis lupus familiaris (Dog) (Canis familiaris)
Status
Reviewed-Annotation score: -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.

Pathwayi: gluconeogenesis

This protein is involved in the pathway gluconeogenesis, which is part of Carbohydrate biosynthesis.
View all proteins of this organism that are known to be involved in the pathway gluconeogenesis and in Carbohydrate biosynthesis.
