1,4-alpha-glucan branching enzyme GlgB

Gene

glgB

Organism
Butyrivibrio fibrisolvens
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

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.By similarity

Catalytic activityi

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

Pathwayi: glycogen biosynthesis
