Phosphofructokinase

Phosphofructokinase, a crucial glycolytic enzyme, catalyzes the conversion of fructose-6-phosphate to fructose-1,6-bisphosphate in the glycolysis pathway. Its activity is inhibited by the binding of Phosphoenolpyruvate (PEP), which regulates the rate of glycolysis. Additionally, Phosphofructokinase is utilized in the measurement of fructose-6-phosphate (fructose-6-phosphate) levels.
