Functioni

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.UniRule annotation

Catalytic activityi

GTP + oxaloacetate = GDP + phosphoenolpyruvate + CO2.UniRule annotation

Cofactori

Mn2+UniRule annotationNote: Binds 1 Mn2+ ion per subunit.UniRule annotation

Pathwayi: gluconeogenesis

This protein is involved in the pathway gluconeogenesis, which is part of Carbohydrate biosynthesis.UniRule annotation
