Conversion of oxaloacetate to phosphoenolpyruvate
PEP carboxykinase uses GTP to decarboxylate and phosphorylate oxaloacetate.
Gluconeogenesis · irreversibleUses GTP to convert oxaloacetate to phosphoenolpyruvate and carbon dioxide.
Phosphoenolpyruvate carboxykinase (cytosolic) is a protein that speeds up a chemical reaction. Cells can adjust when and how strongly many enzymes work.
