ENZYME entry: EC 3.2.1.3

Accepted Name
glucan 1,4-alpha-glucosidase.
Alternative Name(s)
4-alpha-D-glucan glucohydrolase.
amyloglucosidase.
exo-1,4-alpha-glucosidase.
gamma-amylase.
glucoamylase.
lysosomal alpha-glucosidase.
Reaction catalysed
Hydrolysis of terminal (1->4)-linked alpha-D-glucose residues successively from non-reducing ends of the chains with release of beta-D-glucose
Comment(s)
  • Most forms of the enzyme can rapidly hydrolyze 1,6-alpha-D-glucosidic bonds when the next bond in the sequence is 1,4, and some preparations of this enzyme hydrolyze 1,6- and 1,3-alpha-D-glucosidic bonds in other polysaccharides.
  • This entry covers all such enzymes acting on polysaccharides more rapidly than on oligosaccharides.
  • EC 3.2.1.20 from mammalian intestine can catalyze similar reactions.
