ENZYME entry: EC 3.2.1.33

Accepted Name
Amylo-alpha-1,6-glucosidase.
Alternative Name(s)
Amylo-1,6-glucosidase.
Dextrin 6-alpha-D-glucosidase.
Reaction catalysed
Hydrolysis of (1->6)-alpha-D-glucosidic branch linkages in glycogen phosphorylase limit dextrin
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.
