Glucan 1,4-alpha-maltohexaosidase
Glucan 1,4-alpha-maltohexaosidase (EC 3.2.1.98, exo-maltohexaohydrolase, 1,4-alpha-D-glucan maltohexaohydrolase) is an enzyme with systematic name 4-alpha-D-glucan maltohexaohydrolase.[1][2] This enzyme catalyses the following chemical reaction
- Hydrolysis of (1->4)-alpha-D-glucosidic linkages in amylaceous polysaccharides, to remove successive maltohexaose residues from the non-reducing chain ends
