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.
