This enzyme has been studied primarily in plants, but it has been studied in some bacteria as well.[1] It is a key enzyme in gluconeogenesis and photosynthesis that is responsible for reversing the reaction performed by pyruvate kinase in Embden-Meyerhof-Parnas glycolysis. It should not be confused with pyruvate, water dikinase.
It belongs to the family of transferases, to be specific, those transferring phosphorus-containing groups (phosphotransferases) with paired acceptors (dikinases). This enzyme participates in pyruvate metabolism and carbon fixation.
