Question:

Describe the function of the glycogen branching enzyme.

Rebecca A.
Answer:

This enzyme breaks a glycosidic linkage in a glycogen chain at least 11 monomers long producing a chain of 7 residues in length. It then catalyzes the formation of an alpha-1-6 linkage between the 7 residue chain and the pre-existing chain. this forms a new branch point at least 4 residues away from the previous branch site. This is done using the reducing end of the fragment.
