| catalytic Activity | CATALYTIC ACTIVITY: Reaction=Transfers a segment of a (1->4)-alpha-D-glucan chain to a primary hydroxy group in a similar glucan chain.; EC=2.4.1.18; |
| DNA Binding | |
| EC Number | 2.4.1.18 |
| Enzyme Function | FUNCTION: Catalyzes the formation of the alpha-1,6-glucosidic linkages in starch by scission of a 1,4-alpha-linked oligosaccharide from growing alpha-1,4-glucan chains and the subsequent attachment of the oligosaccharide to the alpha-1,6 position. |
