Yeast phosphofructokinase does not exhibit any cold sensitivity. The kinetic properties of the enzyme have been investigated in the range between 10 degrees C and 30 degrees C in dependence on fructose 6-phosphate and ATP. Although a significant increase in the enzyme activity with rising temperature does not occur, the shape of the ATP velocity curves is not markedly altered. With increasing concentrations of fructose-6-phosphate the efficiency of temperature on the catalytic process increases, indicating a small temperature effect on the shape of the fructose-6-phosphate velocity curves. The results are interpreted in terms of an adequate kinetic model.
