product information

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


overexpressed cytosolic fructose 1,6 bisphosphatase (cFBPase) derived from the sequence from Arabidopsis thaliana cFBPase Q9MA79

Host Rabbit
Clonality Polyclonal
Purity Serum
Format Lyophilized
Quantity 100 ĩl
Reconstitution For reconstitution add 100 ĩl of sterile water

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.

Additional information

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.

Additional information

for image of detection please refer to Strand et al. 2000. This antibody does not react with chloroplastic form of FBPase.

Will this antibody be good as a cytosolic (non-microsomal control) in Arabidopsis thaliana roots? Although it has never been tested there is every likelihood that cFBPase will be expressed at reasonable levels even in roots. Even though the biosynthetic flux through to Sucrose may not be high as in mesophyll cells, central metabolism will still be active in young roots and the Sucrose etc being supplied externally still needs to be utilised.
