    Functioni

    Synthase catalytic subunit of the trehalose synthase complex that catalyzes the production of trehalose from glucose-6-phosphate and UDP-glucose in a two step process. Can function independently of the complex.1 Publication

    Catalytic activityi

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

    Enzyme regulationi

    Activated by fructose 6-phosphate. Inorganic phosphate inhibits the synthase activity in the complex, but activates the synthase activity in the free monomeric form.1 Publication
