Reaction mechanism of erythrocyte phosphofructokinase

Abstract:
The reaction mechanism of erythrocyte phosphofructokinase (PFK) was investigated by the initial velocity and the product inhibition. Intersecting lines obtained with initial velocity studies are consistent with a sequential mechanism and the formation of ternary complex as an intermediate. The product inhibition studies support an ordered Bi Bi mechanism in which fructose 6 phosphate (F6P) is the first substrate binding and adenosine diphosphate (ADP) is dissociated from the enzyme before fructose-1,6-P2 (FDP).
