1,4-alpha-glucan branching enzyme GlgB

Gene

glgB

Organism
Synechococcus elongatus (strain PCC 7942) (Anacystis nidulans R2)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-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.

Temperature dependencei

Optimum temperature is about 35 degrees Celsius.

Pathway: glycogen biosynthesis

This protein is involved in the pathway glycogen biosynthesis, which is part of Glycan biosynthesis.
View all proteins of this organism that are known to be involved in the pathway glycogen biosynthesis and in Glycan biosynthesis.
