Accepted name: glucan 1,4-α-maltotetraohydrolase
Reaction: Hydrolysis of (1→4)-α-D-glucosidic linkages in amylaceous polysaccharides, to remove successive maltotetraose residues from the non-reducing chain ends
Other name(s): exo-maltotetraohydrolase; 1,4-α-D-glucan maltotetraohydrolase
Systematic name: 4-α-D-glucan maltotetraohydrolase
Comments: Compare EC β-amylase, which removes successive maltose residues, and EC (glucan 1,4-α-maltohexaosidase) and EC (glucan 1,4-α-maltotriohydrolase).
