May serve as an alternate pathway for starch digestion when luminal alpha-amylase activity is reduced because of immaturity or malnutrition. May play a unique role in the digestion of malted dietary oligosaccharides used in food manufacturing..
Hydrolysis of terminal, non-reducing (1->4)- linked alpha-D-glucose residues with release of alpha-D-glucose.
Hydrolysis of terminal (1->4)-linked alpha-D- glucose residues successively from non-reducing ends of the chains with release of beta-D-glucose.
