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. Also catalyzes the conversion of NAADPH,
CC       which is produced by enzymes such as DUOX1, DUOX2 and NOX5 from NAADP
CC       and promotes Ca(2+) signaling during T cell activation, back to NAADP.
CC       {ECO:0000256|ARBA:ARBA00094433}.
CC   -!- FUNCTION: Cytosolic glucose-6-phosphate dehydrogenase that catalyzes
CC       the first and rate-limiting step of the oxidative branch within the
CC       pentose phosphate pathway/shunt, an alternative route to glycolysis for
CC       the dissimilation of carbohydrates and a major source of reducing power
CC       and metabolic intermediates for fatty acid and nucleic acid
CC       biosynthetic processes. {ECO:0000256|ARBA:ARBA00002914}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-glucose 6-phosphate + NADP(+) = 6-phospho-D-glucono-1,5-
CC         lactone + NADPH + H(+); Xref=Rhea:RHEA:15841, ChEBI:CHEBI:15378,

CC   -!- PATHWAY: Carbohydrate degradation; pentose phosphate pathway; D-
CC       ribulose 5-phosphate from D-glucose 6-phosphate (oxidative stage): step
CC       1/3. {ECO:0000256|ARBA:ARBA00004937}.
CC   -!- SUBUNIT: Homotetramer; dimer of dimers. Interacts with SIRT2; the
CC       interaction is enhanced by H(2)O(2) treatment. Forms a ternary complex
CC       with ALDOB and TP53; this interaction is direct. ALDOB stabilizes the
CC       complex inhibiting G6PD activity and keeping oxidative pentose
CC       phosphate metabolism in check. {ECO:0000256|ARBA:ARBA00046472}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000256|ARBA:ARBA00004496}.
CC   -!- SIMILARITY: Belongs to the glucose-6-phosphate dehydrogenase family.
CC       {ECO:0000256|ARBA:ARBA00009975}.
