| - | α-Glucosidase (E.C.3.2.1.20) is a carbohydrate-hydrolyzing enzyme, which generally cleaves α-1,4 glycosidic bonds of oligosaccharides and starch from the non-reducing ends. However, α-glucosidase from ''Weissella cibaria'' BBK-1 (''Wc''AG) exhibited distinct hydrolysis activity against α-1,4 linkages of short chain oligosaccharides from the reducing end. It prefers to hydrolyse <scene name='88/886503/Cv/8'>maltotriose</scene> and <scene name='88/886503/Cv/10'>acarbose</scene>, while it cannot hydrolyse cyclic oligosaccharides and polysaccharides. <scene name='88/886503/Cv/19'>A monomer of WcAG</scene>. Blue represents Domain A, whereas Domain B, C, and N are shown in yellow, red, and green, respectively. Calcium ion is in magenta. | + | α-Glucosidase (E.C.3.2.1.20) is a carbohydrate-hydrolyzing enzyme, which generally cleaves α-1,4 glycosidic bonds of oligosaccharides and starch from the non-reducing ends.
