| Sysname |
4-alpha-D-glucan maltotetraohydrolase
|

| Reaction(IUBMB) |
Hydrolysis of (1->4)-alpha-D-glucosidic linkages in amylaceous polysaccharides, to remove successive maltotetraose residues from the non-reducing chain ends
|
|---|
| Comment |
Compare EC 3.2.1.2 beta-amylase, which removes successive maltose residues, and EC 3.2.1.98 (glucan 1,4-alpha-maltohexaosidase) and EC 3.2.1.116 (glucan 1,4-alpha-maltotriohydrolase).
