产品介绍： SPSA1 catalyzes the rate-limiting step of sucrose biosynthesis from UDP-glucose and fructose-6-phosphate. It plays a role in regulation of carbon partitioning in the leaves of plants. Furthermore, it is important for sucrose availability which is essential for plant growth and fiber elongation. SPSA1 is also necessary for nectar secretion.Alternative names: Sucrose-phosphate synthase 1, SPS1, Sucrose-phosphate synthase 1F, SPS1F, Sucrose-phosphate synthase 5.1, SPS5.1, UDP-glucose-fructose-phosphate glucosyltransferase
