  • The polysaccharide GtfA reuteran is a unique, soluble glucan produced from sucrose by the glucansucrase GtfA-ΔN of Lactobacillus reuteri 121. The brached structure contains mainly α(1→4) and α(1→6) glucosidic linkages, with no repeating units present. The production of glucans using Lacotobacillus reuteri strains is Generally Recognized as Safe (GRAS), and the compound has potential prebiotic properties.

  • The polysaccharide GtfO-∆N reuteran is a soluble glucan produced from sucrose by the glucansucrase GtfO of Lactobacillus reuteri ATCC 55730 (LB BIO). The brached structure contains mainly α(1→4) and α(1→6) glycosidic linkages, without repeating units present. The polymer contains a large amount of α(1→4) linkages (~80 %). The production of glucans using Lacotobacillus reuteri strains is Generally Recognized as Safe (GRAS), and the compound has potential prebiotic properties.

  • The exopolysaccharide Gtf180 dextran is produced using glucose by the glucansucrase of Lactobaccillus reuteri 180. The heavily branched α-D-glucan has a heterogeneous structure containing (α1→3) and (α1→6) glucosidic linkages with no repeating units present. The terminal positions only carries -α-D-Glcp-(α1→6) units, whether all the -α-D-Glcp-(α1→3)- units are 6-substituted. The polysaccharide is formed from different isomalto-oligosaccharides (IMMO), connected by single (α1→3) bridges in linear and branched orientations.

  • The glucansucrase of Lactobacillus reuteri 180 catalysis the synthesis of a diversity of α-glucans from sucrose. An enzyme mutation of Leu940 in domain B significantly changed the linkage and reaction specificity. Compared with GTF180-ΔN, the GTF180-ΔN L940E mutant has an increased percentage (α1→6) linkages, and a decreased percentage of (α1→3) linkages in the product. Furthermore, the enzyme mutant increased polysaccharide synthesis.
