BRITE hierarchy
Sysname
4-alpha-D-glucan alpha-maltohydrolase
Reaction(IUBMB)
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
Comment
Acts on starch and related polysaccharides and oligosaccharides. The product is alpha-maltose; cf. EC 3.2.1.2 beta-amylase.
