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:0000250}.
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 -!- PATHWAY: Carbohydrate degradation; pentose phosphate pathway; D-
CC ribulose 5-phosphate from D-glucose 6-phosphate (oxidative stage): step
CC 3/3.
CC -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the 6-phosphogluconate dehydrogenase family.
CC {ECO:0000305}.
