Exo-1,4-alpha-Glucosidase . gamma-Amylase . Glucoamylase . 1,4-alpha-Glucosidase, Exo . An enzyme that catalyzes the hydrolysis of terminal 1,4-linked alpha-D-glucose residues successively from non-reducing ends of polysaccharide chains with the release of beta-glucose. It is also able to hydrolyze 1,6-alpha-glucosidic bonds when the next bond in sequence is 1,4. . 0.67
