| Accepted name: |
glucan 1,4-α-maltotetraohydrolase |
| Reaction: |
Hydrolysis of (1→4)-α-D-glucosidic linkages in amylaceous polysaccharides, to remove successive maltotetraose residues from the non-reducing chain ends |
| Other name(s): |
exo-maltotetraohydrolase; 1,4-α-D-glucan maltotetraohydrolase |
| Systematic name: |
4-α-D-glucan maltotetraohydrolase |
| Comments: |
Compare EC 3.2.1.2 β-amylase, which removes successive maltose residues, and EC 3.2.1.98 (glucan 1,4-α-maltohexaosidase) and EC 3.2.1.116 (glucan 1,4-α-maltotriohydrolase). |
