Protein

6-phosphogluconate dehydrogenase, decarboxylating

Gene

gnd

Organism
Citrobacter amalonaticus
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Catalyzes the oxidative decarboxylation of 6-phosphogluconate to ribulose 5-phosphate and CO2, with concomitant reduction of NADP to NADPH.By similarity

Catalytic activityi

6-phospho-D-gluconate + NADP+ = D-ribulose 5-phosphate + CO2 + NADPH.

Pathwayi: pentose phosphate pathway

This protein is involved in step 3 of the subpathway that synthesizes D-ribulose 5-phosphate from D-glucose 6-phosphate (oxidative stage).
Proteins known to be involved in the 3 steps of the subpathway in this organism are:
  1. no protein annotated in this organism
  2. no protein annotated in this organism
  3. 6-phosphogluconate dehydrogenase, decarboxylating (gnd)
This subpathway is part of the pathway pentose phosphate pathway, which is itself part of Carbohydrate degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes D-ribulose 5-phosphate from D-glucose 6-phosphate (oxidative stage), the pathway pentose phosphate pathway and in Carbohydrate degradation.
