IntEnz Enzyme Nomenclature
EC 3.2.1.57

Names

Accepted name:
isopullulanase
Systematic name:
pullulan 4-glucanohydrolase (isopanose-forming)

Reaction

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).
