 Glucan 1,4-a-glucosidase

Glucan 1,4-alpha-glucosidase (, "glucoamylase", "amyloglucosidase" ("AMG"), "gamma-amylase", "lysosomal alpha-glucosidase", "acid maltase", "exo-1,4-alpha-glucosidase", "glucose amylase", "gamma-1,4-glucan glucohydrolase", "acid maltase", "1,4-alpha-D-glucan glucohydrolase") is an enzyme located on the brush border of the small intestine with systematic name "4-alpha-D-glucan glucohydrolase".This enzyme catalyses the following chemical reaction

Most forms of the enzyme can rapidly hydrolyse 1,6-alpha-D-glucosidic bonds when the next bond in the sequence is 1,4.
