CC -!- FUNCTION: Probably involved in the osmoprotection via the biosynthesis
CC of trehalose and in the production of glycogen and alpha-glucan via the
CC TreS-Pep2 branch involved in the biosynthesis of maltose-1-phosphate
CC (M1P). Catalyzes the transfer of glucose from UDP-glucose (UDP-Glc) to
CC D-glucose 6-phosphate (Glc-6-P) to form trehalose-6-phosphate. Probably
CC also able to use ADP-Glc, CDP-Glc, GDP-Glc and TDP-Glc as glucosyl
CC donors. {ECO:0000250|UniProtKB:P9WN11}.
