Functioni

Catalytic activityi

D-glyceraldehyde 3-phosphate + phosphate + NAD(P)+ = 3-phospho-D-glyceroyl phosphate + NAD(P)H.

Pathwayi: glycolysis

This protein is involved in step 1 of the subpathway that synthesizes pyruvate from D-glyceraldehyde 3-phosphate.
Proteins known to be involved in the 5 steps of the subpathway in this organism are:
  1. Glyceraldehyde-3-phosphate dehydrogenase 1 (gapA), Glyceraldehyde-3-phosphate dehydrogenase 2 (gapB)
  2. Phosphoglycerate kinase 2 (pgk2), Phosphoglycerate kinase 1 (pgk1)
  3. 2,3-bisphosphoglycerate-independent phosphoglycerate mutase 2 (gpmI2), 2,3-bisphosphoglycerate-independent phosphoglycerate mutase 1 (gpmI1), 2,3-bisphosphoglycerate-dependent phosphoglycerate mutase (gpmA), 2,3-bisphosphoglycerate-independent phosphoglycerate mutase (apgM)
  4. Enolase (eno)
  5. Pyruvate kinase (pyk)
This subpathway is part of the pathway glycolysis, which is itself part of Carbohydrate degradation.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes pyruvate from D-glyceraldehyde 3-phosphate, the pathway glycolysis and in Carbohydrate degradation.
