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

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.
