3.2.1.57 |
| Accepted name: |
isopullulanase |
| Reaction: |
Hydrolysis of pullulan to isopanose (6-α-maltosylglucose) |
| Glossary: |
pullulan = a linear polymer of (1→6)-linked maltotriose units |
| Systematic name: |
pullulan 4-glucanohydrolase (isopanose-forming) |
| Comments: |
The enzyme has practically no action on starch. Panose (4-α-isomaltosylglucose) is hydrolysed to isomaltose and glucose. cf. EC 3.2.1.41 (pullulanase) and EC 3.2.1.135 (neopullulanase). |
