Limit dextrins are degraded by the action of a debranching enzyme that has 2 distinct enzymatic activities.Which enzymatic activities does it carry out?

Question

Quizplus · Accepted Answer

The debranching enzyme that degrades limit dextrins has two enzymatic activities: oligo(α1,4→α1,4)glucanotransferase, which transfers three glucose units from the branch to a neighboring branch, leaving a linear chain of three glucose units, and α(1→6)glucosidase, which cleaves the remaining α(1→6) bonds at the branch points, releasing free glucose. This means that choice B, oligo(α1,4→α1,4)glucanotransferase and α(1→6)glucosidase, is the best option.
