Names

Accepted name:
glucan 1,4-α-maltohexaosidase
Other names:
exo-maltohexaohydrolase
maltohexaose-producing amylase
G6-amylase
1,4-α-D-glucan maltohexaohydrolase
Systematic name:
4-α-D-glucan maltohexaohydrolase

Reaction

Comments:

cf. EC 3.2.1.3 glucan 1,4-α-glucosidase, which removes successive glucose residues; EC 3.2.1.2 β-amylase, which removes successive maltose residues; EC 3.2.1.116 glucan 1,4-α-maltotriohydrolase, which removes successive maltotriose units and EC 3.2.1.60 glucan 1,4-α-maltotetraohydrolase, which removes successive maltotetraose residues. The products have the α-configuration.
