IUBMB Comments
This single entry covers a group of enzymes whose specificity is directed mainly towards the exohydrolysis of (1->4)-alpha-glucosidic linkages, and that hydrolyse oligosaccharides rapidly, relative to polysaccharide, which are hydrolysed relatively slowly, or not at all. The intestinal enzyme also hydrolyses polysaccharides, catalysing the reactions of EC 3.2.1.3 glucan 1,4-alpha-glucosidase and, more slowly, hydrolyses (1->6)-alpha-D-glucose links.
