Protein

Alpha,alpha-trehalose-phosphate synthase [UDP-forming] A

Gene

tpsA

Organism
Dictyostelium discoideum (Slime mold)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at transcript leveli

Functioni

Synthesizes trehalose 6-phosphate, the precursor for the production of trehalose, the main carbohydrate storage reserve of the dormant spore. Trehalose accumulates in both prestalk and prespore cells and then is rapidly metabolized during terminal differentiation of stalk cells, while being stored in spores, where it serves as the principal energy and carbon source for germination.1 Publication

Catalytic activityi

UDP-glucose + D-glucose 6-phosphate = UDP + alpha,alpha-trehalose 6-phosphate.
