The enzyme GtfML4 of Lactobacillus reuteri strain ML4 is a 4,6-α-glucanotransferase converting pure malto-oligosaccharide substrates (≥ Dp 4) into linear oligosaccharide and polymer products. Using maltheptaose (Dp 7) as starting material, the products contain ~50 % α(1→4)-, and ~50 % α(1→6) linkages. GtfML4 synthesizes mainly α(1→6) linkages, which ensurs that the products are water-soluble. The polysaccharide product could be used as 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.
