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}.
