BACKGROUND: Compound 2-O-α-D-glucosylglycerol (2αGG) naturally served as compatible osmolytes in acclimation to environmental stresses, such as high osmolarity, dryness, and extreme temperature. It presented several bioactivities and has been used in food, agriculture, and cosmetics area. RESULTS: In this work, we attempted to synthesize the 2αGG from low-cost maltodextrin and glycerol through constructing in vitro multienzyme system. It contained two core enzymes, namely, glucan phosphorylases (GPs) and glucosylglycerol phosphorylases (GGPs), and two auxiliary enzymes, namely, isoamylase and 4-α-glucanotransferase...
