General annotation (Comments)

Function

Catalyzes the oxidative decarboxylation of 6-phosphogluconate to ribulose 5-phosphate and CO2, with concomitant reduction of NADP to NADPH By similarity.

Catalytic activity

6-phospho-D-gluconate + NADP+ = D-ribulose 5-phosphate + CO2 + NADPH.

Pathway

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

Subunit structure

Homodimer By similarity.

Sequence similarities

Belongs to the 6-phosphogluconate dehydrogenase family.
