Protein
1,4-alpha-glucan branching enzyme GlgB
Gene
glgB
Organism
Prochlorococcus marinus (strain MIT 9313)
Status
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
: glycogen biosynthesis Pathwayi
This protein is involved in the pathway glycogen biosynthesis, which is part of Glycan biosynthesis.UniRule annotationView all proteins of this organism that are known to be involved in the pathway glycogen biosynthesis and in Glycan biosynthesis.
