Trehalose is a natural non-reducing disaccharide found in plants, invertebrates, fungi, and bacteria.[1] [2] In addition to roles as an energy source and stress protectant, trehalose can function as a signaling molecule. [3][4] Trehalose 6-phosphate is an intermediate in the biosynthesis of trehalose. It is generated from UDP-glucose and glucose 6-phosphate by trehalose 6-phosphate synthase (TPS or otsA).[5] In plants, changes in trehalose 6-phosphate levels positively correlate with diurnal changes in sucrose and may regulate diverse processes, including starch degradation and flowering.[3][6]
海藻糖是一种天然的非还原性二糖,存在于植物、无脊椎动物、真菌和细菌中。[1] [2]除了作为能源和压力保护剂的作用外,海藻糖还可以作为信号分子发挥作用。 [3][4] 海藻糖 6-磷酸是海藻糖生物合成的中间体。它是由海藻糖 6-磷酸合酶(TPS 或 otsA)从 UDP-葡萄糖和葡萄糖 6-磷酸生成的。 [5]在植物中,海藻糖 6-磷酸水平的变化与蔗糖的昼夜变化呈正相关,并可能调节多种过程,包括淀粉降解和开花。[3][6]
