CC   -!- FUNCTION: Catalyzes the oxidative decarboxylation of 6-phosphogluconate
CC       to ribulose 5-phosphate and CO(2), with concomitant reduction of NADP
CC       to NADPH. {ECO:0000256|PIRNR:PIRNR000109}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=6-phospho-D-gluconate + NADP(+) = CO2 + D-ribulose 5-phosphate
CC         + NADPH; Xref=Rhea:RHEA:10116, ChEBI:CHEBI:16526, ChEBI:CHEBI:57783,
CC         ChEBI:CHEBI:58121, ChEBI:CHEBI:58349, ChEBI:CHEBI:58759; EC=1.1.1.44;

CC         ECO:0000256|RuleBase:RU000485};
CC   -!- PATHWAY: Carbohydrate degradation; pentose phosphate pathway; D-
CC       ribulose 5-phosphate from D-glucose 6-phosphate (oxidative stage): step
CC       3/3. {ECO:0000256|PIRNR:PIRNR000109, ECO:0000256|RuleBase:RU000485}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738,
CC       ECO:0000256|PIRNR:PIRNR000109}.
CC   -!- SIMILARITY: Belongs to the 6-phosphogluconate dehydrogenase family.
