Glucan 1,4-alpha-maltotriohydrolase

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

The products have the α-configuration.
