General annotation (Comments)

Function	Involved in the production of dextran, an extracellular glucan polymer. Ref.1
Catalytic activity	Sucrose + ((1->6)-alpha-D-glucosyl)(n) = D-fructose + ((1->6)-alpha-D-glucosyl)(n+1). Ref.1
Miscellaneous	The dextran produced by Leuconostoc mesenteroides CMG713 has a molecular mass of about 2000 kDa and contains exclusively alpha-(1->6) glycosidic linkages in the main chain.
Sequence similarities	Belongs to the glycosyl hydrolase 70 family.
