FBP — Beta vulgaris subsp. vulgaris

Summary

BvFBP (BVRB_9G221420) on sugar beet chromosome 9 encodes a fructose 1,6-bisphosphate 1-phosphatase, a class-1 FBPase with N-terminal and C-terminal domains that binds metal ions. The enzyme is associated with the Calvin cycle, gluconeogenesis, the pentose-phosphate shunt, and reductive pentose-phosphate cycle, as well as fructose, sucrose, and glutamate metabolism. It is linked to nitrogen utilization, amino acid transport, flavonoid anabolism, cell growth, and photosynthetic rate. The protein localizes to the chloroplast stroma and cytosol. Related genes in other species link the family to fructose-bisphosphatase activity (EC 3.1.3.11).
