'''Phosphoenolpyruvate carboxykinase''' (PEPCK) catalyzes the conversion of oxaloacetate to phosphoenolpyruvate (PEP) and CO<sub>2</sub>. PEPCK is part of the gluconeogenesis pathway<ref>PMID:9242918</ref>. There are 3 types of PEPCK distinguished by the energy source of the reaction which can be GTP, ATP or diphosphate. | '''Phosphoenolpyruvate carboxykinase''' (PEPCK) catalyzes the conversion of oxaloacetate to phosphoenolpyruvate (PEP) and CO<sub>2</sub>.
