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.
