CC -!- FUNCTION: Catalyzes the formation of the alpha-1,6-glucosidic linkages
CC in glycogen by scission of a 1,4-alpha-linked oligosaccharide from
CC growing alpha-1,4-glucan chains and the subsequent attachment of the
CC oligosaccharide to the alpha-1,6 position. {ECO:0000255|HAMAP-
CC Rule:MF_00685}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=Transfers a segment of a (1->4)-alpha-D-glucan chain to a
CC primary hydroxy group in a similar glucan chain.; EC=2.4.1.18;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00685};
CC -!- PATHWAY: Glycan biosynthesis; glycogen biosynthesis.
CC {ECO:0000255|HAMAP-Rule:MF_00685}.
CC -!- SUBUNIT: Monomer. {ECO:0000255|HAMAP-Rule:MF_00685}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 13 family. GlgB
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_00685}.
