6-phosphogluconate dehydrogenase, decarboxylating
6-Phosphonoglucono-D-lactone + Water → 6-Phosphogluconic acid + Hydrogen Ion
D-Ribose 5-phosphate + Xylulose 5-phosphate ↔ D-Glyceraldehyde 3-phosphate + D-Sedoheptulose 7-phosphate
D-Ribulose 5-phosphate ↔ D-Ribose 5-phosphate
D-Glyceraldehyde 3-phosphate + D-Sedoheptulose 7-phosphate ↔ D-Erythrose 4-phosphate + β-D-Fructose 6-phosphate
NADP + β-D-Glucose 6-phosphate → 6-Phosphonoglucono-D-lactone + Hydrogen Ion + NADPH
D-Ribulose 5-phosphate ↔ Xylulose 5-phosphate
6-Phosphogluconic acid + NADP → Carbon dioxide + D-Ribulose 5-phosphate + NADPH
