Linear modified starch produced by GtfW of Lactobacillus reuteri strain DSM 20016
The enzyme GtfW of Lactobacillus reuteri strain DSM 20016 is a 4,6-α-glucanotransferase converting pure malto-oligosaccharide substrates into linear oligosaccharide and polymer products. The products contain ~50 % α(1→4)-, and ~50 % α(1→6) linkages using maltheptaose (Dp 7) as the starting material. GtfW synthesizes mainly α(1→6) linkages, which ensures that the products are water-soluble. The polysaccharide product could be used as a solubilizing agent for improving the solubility of poorly water-soluble compounds like drug molecules. Another purpose of the product could be the application for energy and soft drinks.
