| Abstract: | α-Glucosidases(EC 3.2.1.20) acting on a-glycosidic bonds to produce α-anomeric mono-or oligosaccharides form α-1,4 or α-1,6 glycosidic linkages,or a reverse combination of both of these catalytic activities are discussed.These enzymes can catalyse the hydrolysis of saccharides and promote transglucosylation reactions.The present application and development of α-glucosidases is introduced,involving starch hydrolysis,alcoholic fermentation,production of isomalto-oligosaccharide,chemical synthesis,and the study on metabolic mechanisms,clinical examination,therapy and prevention of human diseases.The report provides reference for related researches. |
