Functioni

Catalytic activityi

2-phospho-D-glycerate = phosphoenolpyruvate + H2O.

Cofactori

Mg2+Note: Mg2+ is required for catalysis and for stabilizing the dimer.

Pathwayi: glycolysis

This protein is involved in step 4 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 (GAPDH), Glyceraldehyde-3-phosphate dehydrogenase (GAPDH), Glyceraldehyde-3-phosphate dehydrogenase (GAPDH)
  2. Phosphoglycerate kinase (PGK1), Phosphoglycerate kinase (PGK1), Phosphoglycerate kinase (PGK1), Phosphoglycerate kinase (PGK)
  3. no protein annotated in this organism
  4. Gamma-enolase (ENO2), Alpha-enolase (ENO1), Beta-enolase (ENO3)
  5. Pyruvate kinase (PKM), Pyruvate kinase PKM (PKM), Pyruvate kinase (PKM)
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.
