ENTRY       EC 3.2.1.98
NAME        Glucan 1,4-alpha-maltohexaosidase
            Exo-maltohexaohydrolase
            Maltohexaose-producing amylase
            G6-amylase
CLASS       Hydrolases
            Glycosidases
            Hydrolysing O-glycosyl compounds
SYSNAME     1,4-alpha-D-Glucan maltohexaohydrolase
REACTION    Hydrolysis of 1,4-alpha-D-glucosidic linkages in amylaceous
            polysaccharides so as to remove successive maltohexaose residues
            from the non-reducing cahin ends
SUBSTRATE   Amylaceous polysaccharide
            H2O
PRODUCT     Maltohexaose
COMMENT     cf. EC 3.2.1.3, Glucan 1,4-alpha-D-glucosidase, which removes
            successive glucose residues; EC 3.2.1.2, beta-amylase, which
            removes successive maltose residues; EC 3.2.1.116, which
            removes successive maltotriose units and EC 3.2.1.60, glucan
            1,4-alpha-maltotetraohydrolase, which removes successive
            maltotetraose residues.  The products have the
            alpha-configuration.
