Fructose-6-phosphate is not a substrate for glucose-6-phosphate dehydrogenase

D-Fructose-6-phosphate was shown not to be a substrate for glucose-6-phosphate dehydrogenases (EC. 1.1.1.49) from human erythrocytes, bovine adrenal, rat liver, three yeasts (brewer's yeast, baker's yeast, and Candida utilis), and Leuconostoc mesenteroides. These findings contrast with those of G.M. Kidder (J. Exp. Zool., 226:385-390, '83).
