1,4-alpha-glucan branching enzyme GlgB

Gene

glgB

Organism
Streptococcus agalactiae serotype V (strain ATCC BAA-611 / 2603 V/R)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Protein inferred from homologyi

Functioni

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.UniRule annotation

Catalytic activityi

Transfers a segment of a (1->4)-alpha-D-glucan chain to a primary hydroxy group in a similar glucan chain.UniRule annotation

Pathwayi: glycogen biosynthesis

This protein is involved in the pathway glycogen biosynthesis, which is part of Glycan biosynthesis.UniRule annotation
