    Comment(s)

    This enzyme hydrolyzes 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 Saccharomyces cerevisiae is in a polypeptide chain containing two active centers.

    The other activity is similar to that of EC 2.4.1.25, which acts on the glycogen phosphorylase limit dextrin chains to expose the single glucose residues, which the 6-alpha-glucosidase activity can then hydrolyze. Together, these two activities constitute the glycogen debranching system.
