Protein

1,4-alpha-glucan branching enzyme GlgB

Gene

glgB

Organism
Dickeya chrysanthemi (Pectobacterium chrysanthemi) (Erwinia chrysanthemi)
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.

Catalytic activityi

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

pH dependencei

Optimum pH is 7.

Temperature dependencei

Optimum temperature is 30 degrees Celsius.

Pathwayi: glycogen biosynthesis

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