Function | Catalyzes the formation of the alpha-1,6-glucosidic linkages in glycogen 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. |
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; |
Pathway | Glycan biosynthesis; glycogen biosynthesis. |
Subunit | Monomer. |
Similarity | Belongs to the glycosyl hydrolase 13 family. GlgB subfamily. |
