SBPASE — Brachypodium distachyon

Summary

BRADI_2G55150V3 (SBPASE) on chromosome 2 of Brachypodium distachyon encodes a sedoheptulose-bisphosphatase (EC 3.1.3.37), a class-I fructose-bisphosphatase family enzyme with both sedoheptulose-bisphosphatase and fructose 1,6-bisphosphate 1-phosphatase activities. The gene is associated with the Calvin cycle, reductive pentose-phosphate cycle, gluconeogenesis, and carbohydrate, sucrose, and starch anabolism. It is linked to leaf development, photosynthetic rate, respiration rate, CO₂ fixation, and photosynthetic carbon metabolism. The product localises to the chloroplast stroma, thylakoid, chloroplast envelope, apoplast, and cytosol. Studies of related genes in other species connect the family to chloroplast biogenesis, photosynthetic capacity, leaf area, and biomass, and to grain yield.
