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. {ECO:0000255|HAMAP-
CC       Rule:MF_01248}.
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; Evidence={ECO:0000255|HAMAP-
CC         Rule:MF_01248};
CC   -!- PATHWAY: Glycan degradation; glycogen degradation. {ECO:0000255|HAMAP-
CC       Rule:MF_01248}.
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 13 family.
CC       {ECO:0000255|HAMAP-Rule:MF_01248}.
