Structural highlights
Function
OTSA_ECOLI 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. Essential for viability of the cells at low temperatures and at elevated osmotic strength.[1] [2] [3]
