Protein

1,4-alpha-glucan branching enzyme GlgB

Gene
glgB, VC_A0016
Organism
Vibrio cholerae serotype O1 (strain ATCC 39315 / El Tor Inaba N16961)
Status
Reviewed - 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 By similarity.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
