Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
Sysname
pullulan 4-glucanohydrolase (isopanose-forming)
Reaction(IUBMB)
Hydrolysis of pullulan to isopanose (6-alpha-maltosylglucose)
Comment
The enzyme has practically no action on starch. Panose (4-alpha-isomaltosylglucose) is hydrolysed to isomaltose and glucose. cf. EC 3.2.1.41 (pullulanase) and EC 3.2.1.135 (neopullulanase).
History
EC 3.2.1.57 created 1972
