Protein

6-phosphogluconate dehydrogenase, decarboxylating

Gene

gnd

Organism
Dictyostelium discoideum (Slime mold)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

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. Glucose-6-phosphate 1-dehydrogenase (g6pd-1)
  2. Probable 6-phosphogluconolactonase (pgl)
  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.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
