3.2.1.60
Glucan 1,4-alpha-maltotetraohydrolase.
based on mapping to UniProt P13507
Hydrolysis of (1->4)-alpha-D-glucosidic linkages in amylaceous polysaccharides, to remove successive maltotetraose residues from the non-reducing chain ends.
-!- Compare EC 3.2.1.2, which removes successive maltose residues, and EC 3.2.1.98 and EC 3.2.1.116.
