Protein

Glucose-6-phosphate 1-dehydrogenase, cytoplasmic isoform 1

Gene

ACG9

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: Annotation score: 5 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 which are involved in membrane synthesis and cell division.

Catalytic activityi

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

Enzyme regulationi

Regulated by metabolites.
