Function
Alpha glucosidase (AGS) or maltase breaks down the 1,4-α bonds in starch or disaccharides to produce glucose. Maltase breaks down maltose. Isomaltase or sucrase-isomaltase or oligo-1,6-glucosidase breaks the 1,6 bond.[1] For details see Sucrase-isomaltase.

Disease
AGS deficiency is the cause of Pompe Disease. AGS inhibitors are used as anti-diabetic drugs and can potentially prevent the fusion of HIV and hepatitis B virus to cells.
