Protein

Glucose-6-phosphate 1-dehydrogenase

Gene

G6PD

Organism
Cricetulus griseus (Chinese hamster) (Cricetulus barabensis griseus)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

Functioni

Catalyzes the rate-limiting step of the oxidative pentose-phosphate pathway, which represents a route for the dissimilation of carbohydrates besides glycolysis. The main function of this enzyme is to provide reducing power (NADPH) and pentose phosphates for fatty acid and nucleic acid synthesis (By similarity).By similarity

Catalytic activityi

D-glucose 6-phosphate + NADP+ = 6-phospho-D-glucono-1,5-lactone + NADPH.
