Fructose 1,6 Bisphosphatase

Cytosolic fructose-1,6-bisphosphatase (cytoFBPase) (EC 3.1.3.11) occupies a strategic site in sucrose synthesis and has been demonstrated to play a key role in carbon partitioning between sucrose and starch in non-sorbitol forming plants. In addition to sucrose and starch, Sorbitol is the primary photosynthetic end product in the leaves of many tree fruit species in the Rosaceae family. To understand the biochemical regulation of photosynthetic carbon partitioning between sorbitol, sucrose and starch in sorbitol synthesizing species, we purified cytoFB-Pase to apparent homogeneity from apple leaves. The enzyme was a homotetramer with a subunit mass of 37 kDa. It was highly specific for fructose-1,6-bisphosphate with a Km of 3.1 μm and a Vmax of 48 units/mg protein. Either Mg2+ or Mn2+ was required for its activity with a Km of 0.59 mm and 62 μM, respectively. Li+, Ca2+, Zn2+, Cu2+ and Hg2+ inhibited whereas Mn2+ enhanced the Mg2+-activated enzyme activity. Fructose-6-phosphate was found to be a mixed type inhibitor with a Ki of 0.47 mm. Fructose 2,6-bisphosphate (F2,6BP) competitively inhibited the enzyme activity and changed the substrate saturation curve from hyperbolic to sigmoidal. Adenosine monophosphate (AMP) was a non-competitive inhibitor for the enzyme. F2,6BP interacted with AMP to inhibit the enzyme in a synergistic way. Dihydroxyacetone phosphate did not have inhibitory effect on apple leaf cytosolic FBPase activity. Sorbitol increased the susceptibility of the enzyme to the inhibition by F1,6BP. The presence of sorbitol in the reaction mixture led to a reduction in the enzyme activity.

Bisphosphatase Deficiency

Abstract Background: Fructose-1,6-bisphosphatase (FBPase) deficiency is a rare disorder of glucose metabolism, mainly revealed by hypoglycemia and lactic acidosis. The disease is caused by a mutation of FBP1 gene, which is clustered in a 31-kb region on chromosome 9q22. Case presentation: We described a two-and-half-year-old boy diagnosed as FBPase deficiency. The result of gene analysis showed that the patient had a compound heterozygote for the G164S and P308R, respectively inherited from his father and mother. To some degree, mutations are associated with activity of enzyme, which is corresponding to the level of glucose and extent of brain damage. Patients are advised to reduce intake of fructose and sucrose and avoid long-term fasting in order to reduce the risk of metabolic decompensation. Conclusions: This report would like to provide profound insights of FBPase deficiency.
