Protein

Phosphoenolpyruvate carboxykinase [GTP], mitochondrial

Gene

Pck2

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

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.By similarity

Miscellaneous

In eukaryotes there are two isozymes: a cytoplasmic one and a mitochondrial one.

Catalytic activityi

GTP + oxaloacetate = GDP + phosphoenolpyruvate + CO2.

Cofactori

Mn2+By similarityNote: Binds 1 Mn2+ ion per subunit.By similarity

Pathwayi: gluconeogenesis

This protein is involved in the pathway gluconeogenesis, which is part of Carbohydrate biosynthesis.
View all proteins of this organism that are known to be involved in the pathway gluconeogenesis and in Carbohydrate biosynthesis.
