Enzyme Information

3.2.1.20
Alpha-glucosidase.
based on mapping to UniProt P10253
Hydrolysis of terminal, non-reducing (1->4)-linked alpha-D-glucose residues with release of alpha-D-glucose.
-!- Group of enzymes whose specificity is directed mainly toward the exohydrolysis of 1,4-alpha-glucosidic linkages, and that hydrolyze oligosaccharides rapidly, relative to polysaccharides, which are hydrolyzed relatively slowly, or not at all. -!- The intestinal enzyme also hydrolyzes polysaccharides, catalyzing the reactions of EC 3.2.1.3, and, more slowly, hydrolyzes 1,6-alpha-D- glucose links.
