애플리케이션

α-Amylase is used to hydrolyze α bonds of α-linked polysaccharides, such as starch and glycogen. α-Amylase has been used in various plant studies, such as metabolism studies in Arabidopsis . Amylases from Aspergillus oryzae are commonly used as baking additives to prevent staling in the baking industry, clarify haze from fruit juices and alcoholic beverages, and to produce glucose and maltose syrup products .

생화학적/생리학적 작용

α-Amylase hydrolyzes the α-(1,4) glucan linkages in polysaccharides of three or more α-(1,4) linked D-glucose units. Natural substrates such as starch and glycogen are broken down into glucose and maltose. The International Union of Immunological Societies (IUIS) has classified α-amylase from Aspergillus oryzae (Asp o II) as an occupational allergen that can cause respiratory symptoms .
