Glucansucrases

  • The N-terminally truncated glucansucrase Gtf180 of Lactobacillus reuteri, belongs to glycosyl hydrolase family GH70. The enzyme synthesizes branched glucans containing 69 % α(1→6)-, and 31 % α(1→3)-glycosidic linkages (dextran) using sucrose as a substrate.

    This product is sold for research use only.
    *Activity was measured by following the release of fructose from sucrose. One unit of enzyme activity is defined as the release of 1 μmol of fructose per minute.

  • The N- and V-terminally truncated glucansucrase Gtf180 of Lactobacillus reuteri 180, belongs to the glycosyl hydrolase family GH70. Compared to Gtf180-ΔN, Gtf180-ΔN-ΔV is impaired in polysaccharide synthesis. Instead this enzyme produces a large number of oligosaccharides. The enzyme forms α(1→6)- and α(1→3)-glycosidic linkages using sucrose as a substrate.

  • The N-terminally truncated enzyme of Lactobacillus reuteri strain ATCC 55730 (LB BIO) is a hydrolytic reuteransucrase producing a soluble glucan, in which the majority ~79 % of the linkages are of the α(1→4) glucosidic type. This reuteran also contains 21 % α(1→6)- linked glucosyl units, and 4,6-disubstituted α-glucosyl units at the branching points.
