CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=Hydrolysis of (1->4)-alpha-D-glucosidic linkages in
CC         polysaccharides so as to remove successive maltose units from the
CC         non-reducing ends of the chains.; EC=3.2.1.2;
CC         Evidence={ECO:0000256|RuleBase:RU000509};
CC   -!- SIMILARITY: Belongs to the glycosyl hydrolase 14 family.
