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 184.108.40.206 (pullulanase) and EC 220.127.116.11 (neopullulanase).
