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 -!- PATHWAY: Glycan biosynthesis; glycogen biosynthesis. CC -!- SUBUNIT: Monomer. CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 13 family. GlgB CC subfamily.
