CC   -!- FUNCTION: Catalyzes the production of trehalose from glucose-6-
CC       phosphate and UDP-alpha-D-glucose in a 2 step process. {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=D-glucose 6-phosphate + UDP-alpha-D-glucose = alpha,alpha-
CC         trehalose 6-phosphate + H(+) + UDP; Xref=Rhea:RHEA:18889,
