α,α-Trehalose 6-phosphate (Tre6P) potassium is an intrinsic 6-phosphate derivative of α,α′-trehalose and acts as an intermediary metabolite. It undergoes enzymatic conversion to the final metabolic product, α,α′-trehalose, via the enzyme Tre6P phosphatase (T6PP).
Trehalose 6-phosphate (T6P) is synthesised from glucose-6-phosphate (G6P) and uridine 5-diphospho-glucose. Trehalose-6-phosphate synthase catalyzes this reaction. T6P serves as a precursor for the synthesis of trehalose. It regulates sugar metabolism in in Arabidopsis plants and promotes its growth.In plants, T6P blocks the action of sucrose nonfermenting-1-related protein kinase 1, which affects the energy and carbon metabolism
