Glucan 1,4-alpha-maltohexaosidase.
based on mapping to UniProt P19571
Hydrolysis of (1->4)-alpha-D-glucosidic linkages in amylaceous polysaccharides, to remove successive maltohexaose residues from the non- reducing chain ends.
-!- Cf. EC 3.2.1.3, which removes successive glucose residues. -!- Cf. EC 3.2.1.2, which removes successive maltose residues. -!- Cf. EC 3.2.1.116, which removes successive maltotriose residues. -!- Cf. EC 3.2.1.60, which removes successive maltotetraose residues. -!- The products have the alpha-configuration.
