Family
Glycosyl hydrolase 31 family
Subcellular location
Apical cell membrane
Function
Alpha-(1,4) exo-glucosidase involved in breakdown of dietary starch oligosaccharides in small intestine. Cleaves the non-reducing alpha-(1,4)-linked glucose residue in linear dextrins with retention of anomeric center stereochemistry. Mainly hydrolyzes short length oligomaltoses having two to seven glucose residues. Can cleave alpha-(1,2), alpha-(1,3) and alpha-(1,6) glycosidic linkages with lower efficiency, whereas beta glycosidic linkages are usually not hydrolyzed.
