KEGG   ENZYME: 3.2.1.60
Entry
EC 3.2.1.60                 Enzyme                                 
Name
glucan 1,4-alpha-maltotetraohydrolase;
exo-maltotetraohydrolase;
1,4-alpha-D-glucan maltotetraohydrolase
Class
Hydrolases;
Glycosylases;
Glycosidases, i.e. enzymes that hydrolyse O- and S-glycosyl compounds
Sysname
4-alpha-D-glucan maltotetraohydrolase
Reaction(IUBMB)
Hydrolysis of (1->4)-alpha-D-glucosidic linkages in amylaceous polysaccharides, to remove successive maltotetraose residues from the non-reducing chain ends
Comment
Compare EC 3.2.1.2 beta-amylase, which removes successive maltose residues, and EC 3.2.1.98 (glucan 1,4-alpha-maltohexaosidase) and EC 3.2.1.116 (glucan 1,4-alpha-maltotriohydrolase).
History
EC 3.2.1.60 created 1972
