The anomeric form of D-fructose 1,6-bisphosphate used as substrate in the muscle and yeast aldolase reactions
K. J. Schray, R. Fishbein, W. P. Bullard and S. J. Benkovic
From a series of rapid quench kinetic experiments, it has been demonstrated
that muscle D-fructose bisphosphate aldolase catalyzes the cleavage of
beta-D-fructose 1,6-bisphosphate but not that of the alpha anomer, although
the alpha anomer may be tightly bound. Yeast D-fructose bisphosphate
aldolase appears to utilize both alpha and beta anomers of the substrate,
with yeast apoaldolase catalyzing the interconversion of the alpha and beta
forms.
