Fructose-1,6-bisphosphatase (EC (FBPase) is a key regulatory enzyme of gluconeogenesis that catalyzes the hydrolysis of fructose-1,6-bisphosphate to generate fructose-6-phosphate and inorganic phosphate.
Under standard reaction conditions that included 1 mM ATP and concentrations of fructose-6-phosphate ranging from 0.1 nM through 1 mM, the Km and Vmax of this PFK activity were determined to be 1.38 [micro]M and 46.0 [micro]M/mg protein/min, respectively.
Sucrose-phosphate synthase was assayed by incubating extract in 75 mM HEPES-KOH (pH 7.4), 3.75 mM Mg[Cl.sub.2], 0.75 mM EDTA, 2.25 mM UDP-Glucose, 15 mM glucose-6-phosphate, 3 mM fructose-6-phosphate (final volume 800 [micro]L).
