One of these enzymes is known as transferase and the other enzyme is known as alpha 13 glucosidase. Now, in eukaryotic cells, these two enzymes are actually found on a single enzyme. So in eukaryotic cells we have this single bifunctional enzyme that contains these two different types of enzymes, transferase and alpha 116 glucosedase, these two different types of catalytic sites that basically catalyze two different types of reactions. So let's begin by examining transferase and what it actually does. So suppose we have the following glycogen molecules. So it's a simple molecule with a single alpha one six glycocitic bond.
