IUBMB Comments
This enzyme hydrolyses an unsubstituted glucose unit linked by an alpha(1->6) bond to an alpha(1->4) glucose chain. The enzyme activity found in mammals and yeast is in a polypeptide chain containing two active centres. The other activity is similar to that of EC 2.4.1.25 (4-alpha-glucanotransferase), which acts on the glycogen phosphorylase limit dextrin chains to expose the single glucose residues, which the 6-alpha-glucosidase activity can then hydrolyse. Together, these two activities constitute the glycogen debranching system.
