General annotation (Comments)

Function

Catalyzes the transfer of glucose from UDP-glucose to glucose-6-phosphate to form alpha,alpha-1,1 trehalose-6-phosphate. Acts with retention of the anomeric configuration of the UDP-sugar donor By similarity.

Catalytic activity

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

Pathway

Glycan biosynthesis; trehalose biosynthesis.

Subunit structure

Homotetramer By similarity.

Sequence similarities

Belongs to the glycosyltransferase 20 family.
