The name of this superfamily has been modified since the most recent official CATH+ release (v4_4_0). At the point of the last release, this superfamily was named:
"Glycosidases
".
FunFam 54: Glycogen debranching enzyme
Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.
There are 7 GO terms relating to "molecular function"
The search results have been sorted with the annotations that are found most frequently at the top of the

Isoamylase activity GO:0019156
Catalysis of the hydrolysis of alpha-(1,6)-D-glucosidic branch linkages in glycogen, amylopectin and their beta-limits dextrins.

Amylo-alpha-1,6-glucosidase activity GO:0004135
Catalysis of the hydrolysis of (1->6)-alpha-D-glucosidic branch linkages in glycogen phosphorylase limit dextrin. Limit dextrin is the highly branched core that remains after exhaustive treatment of glycogen with glycogen phosphorylase. It is formed because these enzymes cannot hydrolyze the (1->6) glycosidic linkages present.

Drug binding GO:0008144
Interacting selectively and non-covalently with a drug, any naturally occurring or synthetic substance, other than a nutrient, that, when administered or applied to an organism, affects the structure or functioning of the organism; in particular, any such substance used in the diagnosis, prevention, or treatment of disease.
