Calvin Cycle & PPP

Rubisco

fixes CO2 to Ribulose-1,5-Bisphosphate forming two 3-Phosphoglycerate (CC 1)

Phosphoglycerate Kinase

Adds phosphate to 3-Phosphoglycerate forming 1,3-bisphosphoglycerate (CC 2)

G3P Dehydrogenase

Reduces 1,3-bisphosphoglycerate to G3P (using 6 NADPHs) (CC 3)

Triose Phosphate Isomerase

Converts G3P reversible to DHAP (CC 4)

Aldolase

Joins/splits sugars G3P + DHAP to form Fructose-1,6-Bisphosphate (CC 5)

Fructose-1,6-Bisphosphatase

Removes phosphate from Fructose-1,6-Bisphosphate to from Fructose-6-Phosphate (CC 6)

Transketolase

Transfer 2C from Fructose-6-P + Glyceraldehyde-3-P to form Erythrose-4-P + Xylulose-7-P (CC 7)

Transaldolase

Transfers 3C from Erythrose-4-P + DHAP to form Sedoheptulose-1,7-Bisphosphate (CC 8)

Sedoheptulose-1,7-Bisphosphatase

Splits Sedoheptulose-1,7-Bisphosphate into Sedoheptulose-7-P + Pi (CC 9)

Transketolase

Splits Sedoheptulose-7-P + Glyceraldehyde-3-P into Ribose-5-P + Xylulose-5-P (TPP-dependent) (CC 10)

Phosphopentose Isomerase

turns Ribose-5-P into Ribulose-5-Phosphate (CC 11)

Phosphopentose Epimerase

turns Xylulose-5-P into Ribulose-5-P (CC 12)

Glucose-6-Phosphate Dehydrogenase

Converts Glucose-6-P into 6-Phosphoglucono-δ-lactone (PPP 1)

Gluconolactonase

Hydrolyzes lactone ring on 6-PG lactone to form 6-Phosphoglutconate (PPP 2)

6-Phosphogluconate Dehydrogenase

Converts 6-Phosphogluconate into Ribulose-5-P + CO2 + NADPH (PPP 3)

Transaldolase

Sedoheptulose-7-P + Glyceraldehyde-3-P → Fructose-6-P + Erythrose-4-P (via Schiff base w/ Lys) (PPP 5)
