Function
function
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 activity
- ATP + D-maltose = ADP + alpha-maltose 1-phosphate + H+
Pathway
Glycan biosynthesis; glycogen biosynthesis.
