cFBPase | cytosolic fructose-1,6-bisphosphatase (cytoplasm marker in photosynthetic tissues))

Fructose-1,6 bisphosphatase (FBPase) (EC=3.1.311)  is one of the regulatory enzymes in the sucrose biosynthetic pathway. In non-photosynthetic tissues, it regulates the rate of gluconeogenesis. In photosynthetic tissues, two FBPase isozymes (chloroplastic and cytosolic) play key roles in carbon assimilation and metabolism. In photosynthetic tissues cFBPase (cytosolic fructose 1,6 bisphosphatase) converts triose phosphates from the chloroplast to sucrose during light hours. Alternative name: D-fructose-1,6-bisphosphate 1-phosphohydrolase

store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.

Kinetic and allosteric properties of the plant cytosolic FBPase are remarkably similar to the mammalian and yeast FBPase, but differ greatly from those of the chloroplastic FBPase. The antibody could detect FBPase from the human COS-7 cell line transfected with FBP1 expressing vector.
