| Accepted name: |
glucan 1,4-α-maltohydrolase |
| Reaction: |
hydrolysis of (1→4)-α-D-glucosidic linkages in polysaccharides so as to remove successive α-maltose residues from the non-reducing ends of the chains |
| Other name(s): |
maltogenic α-amylase; 1,4-α-D-glucan α-maltohydrolase |
| Systematic name: |
4-α-D-glucan α-maltohydrolase |
| Comments: |
Acts on starch and related polysaccharides and oligosaccharides. The product is α-maltose; cf. EC 3.2.1.2 β-amylase. |
