Description
Glucan 1,4-alpha-maltohydrolase (EC 3.2.1.133, maltogenic alpha-amylase, 1,4-alpha-D-glucan alpha-maltohydrolase) is an enzyme with system name 4-alpha-D-glucan alpha-maltohydrolase. This enzyme catalyses the following chemical reaction:hydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides so as to remove successive alpha-maltose residues from the non-reducing ends of the chains. This enzyme acts on starch and related polysaccharides and oligosaccharides.
