Comments
[?]
FUNCTION | Removes maltotriose and maltotetraose chains that are attached by 1,6-alpha-linkage to the limit dextrin main chain, generating a debranched limit dextrin. |
CATALYTIC ACTIVITY | Reaction=Hydrolysis of (1->6)-alpha-D-glucosidic linkages to branches with degrees of polymerization of three or four glucose residues in limit dextrin.; EC=3.2.1.196; |
PATHWAY | Glycan degradation; glycogen degradation. |
SIMILARITY | Belongs to the glycosyl hydrolase 13 family. |
