Protein

Alpha,alpha-trehalose-phosphate synthase [UDP-forming] 56 kDa subunit

Gene

TPS1

Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

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
