CC   -!- FUNCTION: Catalyzes the rate-limiting step of the oxidative pentose-
CC       phosphate pathway, which represents a route for the dissimilation of
CC       carbohydrates besides glycolysis. The main function of this enzyme is
CC       to provide reducing power (NADPH) and pentose phosphates for fatty acid
CC       and nucleic acid synthesis (By similarity).
CC       {ECO:0000250|UniProtKB:Q9LK23}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-glucose 6-phosphate + NADP(+) = 6-phospho-D-glucono-1,5-
CC         lactone + H(+) + NADPH; Xref=Rhea:RHEA:15841, ChEBI:CHEBI:15378,
CC         ChEBI:CHEBI:57783, ChEBI:CHEBI:57955, ChEBI:CHEBI:58349,
CC         ChEBI:CHEBI:61548; EC=1.1.1.49;
CC         Evidence={ECO:0000250|UniProtKB:Q9LK23};
CC   -!- PATHWAY: Carbohydrate degradation; pentose phosphate pathway; D-
CC       ribulose 5-phosphate from D-glucose 6-phosphate (oxidative stage): step
CC       1/3. {ECO:0000305}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:Q9LK23}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:Q9LK23}.
CC   -!- SIMILARITY: Belongs to the glucose-6-phosphate dehydrogenase family.
CC       {ECO:0000305}.
