DE   reuteransucrase.
CA   formation of reuteran from sucrose.
CC   -!- The glucansucrases transfer a D-glucosyl residue from sucrose to a
CC       glucan chain.
CC   -!- They are classified based on the linkage of the transferred glucosyl
CC       residue.
CC   -!- The enzyme, characterized from the lactic acid bacterium
CC       Limosilactobacillus reuteri strain 121, catalyzes the hydrolysis of
CC       sucrose and the transfer of the D-glucose moiety to suitable
CC       acceptors (inclduing sucrose), forming the glucan reuteran, which is
CC       typical for these strains.
CC   -!- The enzyme forms mostly alpha(1->4) glucosidic linkages, but also
CC       alpha(1->6) linkages.
CC   -!- The presence of maltose significantly accelerate the initial rate of
CC       the reaction. See EC 2.4.1.5.
