    Functioni

    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.By similarity

    Catalytic activityi

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