Background

Fructose-1,6 bisphosphatase (FBPase) 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.
