General annotation (Comments)

Function

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 activity

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

Enzyme regulation

Regulated by metabolites.

Pathway

Carbohydrate degradation; pentose phosphate pathway; D-ribulose 5-phosphate from D-glucose 6-phosphate (oxidative stage): step 1/3.

Subunit structure

Homodimer By similarity.

Subcellular location

Cytoplasm.

Miscellaneous

There are 6 glucose-6-phosphate 1-dehydrogenase genes in A.thaliana.

Sequence similarities

Belongs to the glucose-6-phosphate dehydrogenase family.
