NiceZyme View of ENZYME: EC 3.2.1.20

Accepted Name
Alpha-glucosidase.
Alternative Name(s)
Acid maltase.
Glucoinvertase.
Glucosidosucrase.
Lysosomal alpha-glucosidase.
Maltase.
Maltase-glucoamylase.
Reaction catalysed
Hydrolysis of terminal, non-reducing (1->4)-linked alpha-D-glucose residues with release of alpha-D-glucose
Comment(s)
  • 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.
