BRITE hierarchy
Sysname
4-alpha-D-glucan maltotriohydrolase
Reaction(IUBMB)
Hydrolysis of (1->4)-alpha-D-glucosidic linkages in amylaceous polysaccharides, to remove successive maltotriose residues from the non-reducing chain ends
Comment
cf. EC 3.2.1.2 (beta-amylase), EC 3.2.1.60 (glucan 1,4-alpha-maltotetraohydrolase) and EC 3.2.1.98 (glucan 1,4-alpha-maltohexaosidase). The products have the alpha-configuration.
