Which statement is TRUE of the glycogen branching enzyme?
A) It catalyzes glycogen degradation by removing glucose from the branch points.
B) It catalyzes the formation of an $\alpha$ 1-4 linkages during glycogen synthesis.
C) It catalyzes the addition of a glucose molecule to glycogenin.
D) It is allosterically regulated by fructose 2,6-bisphosphate.
E) It is an enzyme that belongs to a family of transferases.

Question

Quizplus · Accepted Answer

The glycogen branching enzyme is indeed a type of transferase, which is a family of enzymes that catalyze the transfer of a functional group from one molecule to another. This enzyme specifically transfers a block of oligoglucose from one part of a glycogen molecule to another, creating a branch point through an alpha-1,6 glycosidic bond, thereby contributing to the branched structure of glycogen.
