Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

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 By similarity.
Catalytic activity	Transfers a segment of a (1->4)-alpha-D-glucan chain to a primary hydroxy group in a similar glucan chain. HAMAP MF_00685
Pathway	Glycan biosynthesis; glycogen biosynthesis. HAMAP MF_00685
Subunit structure	Monomer By similarity.
Sequence similarities	Belongs to the glycosyl hydrolase 13 family.
