Function
function
Catalyzes the conversion of oxaloacetate (OAA) to phosphoenolpyruvate (PEP), the rate-limiting step in the metabolic pathway that produces glucose from lactate and other precursors derived from the citric acid cycle.
Catalytic activity
- oxaloacetate + GTP = phosphoenolpyruvate + GDP + CO2
Cofactor
Note: Binds 1 Mn2+ ion per subunit.
Pathway
Carbohydrate biosynthesis; gluconeogenesis.
