CC   -!- FUNCTION: Involved in the production of dextran, an extracellular
CC       glucan polymer. {ECO:0000269|Ref.1}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[(1->6)-alpha-D-glucosyl](n) + sucrose = [(1->6)-alpha-D-
CC         glucosyl](n+1) + D-fructose; Xref=Rhea:RHEA:18825, Rhea:RHEA-

CC         Evidence={ECO:0000269|Ref.1};
CC   -!- MISCELLANEOUS: The dextran produced by Leuconostoc mesenteroides CMG713
CC       has a molecular mass of about 2000 kDa and contains exclusively alpha-
CC       (1->6) glycosidic linkages in the main chain.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 70 family. {ECO:0000255}.
