Phosphofructokinase catalyzes the conversion of -6-phosphate to fructose-1,6-diphosphate. of glycolysis is usually explained in terms of properties of three enzymes: hexokinase, phosphofructokinase pyruvate kinase. Recently Beutler that phosphofructokinase (PFK) of erythrocytes is inhibited by 2,3-DPG. It is that the concentration of 2,3-DPG in erythrocytes very high. In view of control of glycolysis the by Beutler is very important. However, our results are in disagreement with those of Beutler.
