Phosphofructokinase glycolysis
WebFeb 6, 2024 · F2,6BP is controlled by phosphofructokinase-2/fructose-2,6-bisphosphatases (PFKFBs), a family of bifunctional enzyme that contains a kinase and a phosphatase domain and catalyzes the synthesis... WebPhosphofructokinase plays an important catalytic role in transient glycolysis that enables mitochondrial fusion and the stimulation of the S phase entry. This protein is necessary to upregulate glycolysis at this stage of the cell cycle (8). Elevated temperatures can hasten pH decline until phosphofructokinase loses its activity.
