additional information hydrolyses by detaching one maltose unit, recognizes maltose residues at non-reducing end of various maltosides and hydrolyzes (1, 4)-, (1, 2)-, (1, 3)-and (1, 6)-alpha-D-glucosidic linkages and the glucosidic linkages between D-glucose and phenol, D-glucose and D-glucitol, and D-glucose and D-fructose adjacent to the maltose molecule Weizmannia coagulans ?
