Glucan 1,4-α-maltotetraohydrolase

Glucan 1,4-α-maltotetraohydrolase (, exo-maltotetraohydrolase, 1,4-α- D -glucan maltotetraohydrolase) is an enzyme with systematic name 4-α- D -glucan maltotetraohydrolase. It catalyses the hydrolysis of (1→4)-α- D -glucosidic linkages in amylaceous polysaccharides, to remove successive maltotetraose residues from the non-reducing chain ends
