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.
