Fructose-1,6-Bisphosphatase (F1,6BPase)

F1,6BPase is an enzyme in gluconeogenesis that catalyzes hydrolysis of fructose-1,6-bisphosphate, producing fructose-6-phosphate and Pi.

> Fructose-1,6-Bisphosphate + H 2O <=> Fructose-6-Phosphate + Pi

F1,6BPase is a key regulatory enzyme of gluconeogenesis. It is allosterically inactivated by fructose-2,6-bisphosphate and AMP (Figures 16.6 and 16.7). Synthesis of F1,6BPase is also regulated hormonally.
