Fructose-1,6-bisphosphatase (FBP) is an important enzyme in glucose metabolism. It catalyzes the hydrolysis of fructose-1,6-bisphosphate to fructose-6-phosphate and inorganic phosphate. Fructose-6-phosphate kinase converts fructose-6-phosphate into fructose 1,6-bisphophate in the rate limiting step of the glycolysis cycle.http://www.creative-enzymes.com/product/Native-Propionibacterium-Freudenreichii-shermanii-Fructose6phosphate-Kinase-Pyrophosphatedependent_1179.html
