2. The inhibition of Fructose 1,6-bisphosphatase is maybe a form of controlling diabetes. Fructose 1,6-bisphosphatase is one of the enzymes used in the synthesis of glucose. They looked at three possible inhibitor points: 1. the active site for 1,6-bisphosphatase, 2. An allosteric binding site for AMP, and 3. A tetrameric binding site at the dimer interface. The leading compounds for inhibiting fructose 1,6-bisphosphates is organofluorines. Through this research they found three inhibitors. It is a really interesting that an inhibitor of this protein can help treat diseases like diabetes.

Novel Heteroaromatic Organofluorine Inhibitors of Fructose-1,6-bisphosphatase
3. Fructose 1,6-bisphosphatase has multiple subunits that allows it to change from R state to T state. This paper looks at the conformational change of the protein. The dimers shift 17 degrees from each other. This change the Arg-22 residue to go from interacting with Glu-108 and Arg-110 to Thr-27 and Glu-29. To see if the arginine was important part of the protein functionality, they converted it to an alanine. They looked at the differences in the catalytic ability of R-state vs. T state. Through their research they found that the Arg22 to Ala has no effect on the enzyme and the R-state enhances catalytic potential. This research shows that the arginine is only part of the catalytic properties of the enzyme.
