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 (1->6)-alpha-glucose residue
that forms a branch point on an alpha-(1->4)-linked 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.
