6-phosphofructokinase liver type is an enzyme that in humans is encoded by the PFKL gene.Phosphofructokinase (PFK) is a tetrameric enzyme that catalyzes a key step in glycolysis namely the conversion of D-fructose 6-phosphate to D-fructose 16-bisphosphate. Separate genes encode a muscle subunit (M) and a liver subunit (L).
