Function

function

Synthase catalytic subunit of the trehalose synthase complex that catalyzes the production of trehalose from glucose-6-phosphate and UDP-alpha-D-glucose in a two step process (PubMed:21931609).
The disaccharide trehalose serves as a storage carbohydrate that is mobilized during spore germination (PubMed:21931609).

Catalytic activity
