Function
function
Catalyzes the reversible conversion of 2-phosphoglycerate (2-PG) into phosphoenolpyruvate (PEP). It is essential for the degradation of carbohydrates via glycolysis.
Catalytic activity
- (2R)-2-phosphoglycerate = H2O + phosphoenolpyruvate
Cofactor
Protein has several cofactor binding sites:
Note: Binds a second Mg2+ ion via substrate during catalysis.
Note: Mg2+ is required for catalysis and for stabilizing the dimer.
Pathway
Carbohydrate degradation; glycolysis; pyruvate from D-glyceraldehyde 3-phosphate: step 4/5.
