DE   RecName: Full=Glycogen debranching enzyme;
DE            EC=3.2.1.196;
DE   AltName: Full=Limit dextrin alpha-1,6-maltotetraose-hydrolase;
GN   Name=glgX;
XX
CC   -!- FUNCTION: Removes maltotriose and maltotetraose chains that are
CC       attached by 1,6-alpha-linkage to the limit dextrin main chain,
CC       generating a debranched limit dextrin.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Hydrolysis of (1->6)-alpha-D-glucosidic linkages to branches
CC         with degrees of polymerization of three or four glucose residues in
CC         limit dextrin.; EC=3.2.1.196;
CC   -!- PATHWAY: Glycan degradation; glycogen degradation.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 13 family.
