What is α-Amylase?
The Uses of α-Amylase
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 1 . 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.
The Uses of α-Amylase
Preparing the Japanese national drink "sake"; in converting maizes into sugar in manufacture of whiskey.
The Uses of α-Amylase
α-Amylase has been used:
- as a control enzyme in agar plate-based and carboxymethylcellulose-based clearing assays to screen cellulase activity
- for the hydrolysis of starch to explore the the role of wheat starch in frozen dough
- to inhibit Staphylococcus aureus biofilms
General Description
α-Amylase is also referred as taka-amylase A.
Biochem/physiol Actions
Aspergillus oryzae α-amylase (Ao α-amylase) enzyme catalyzes the hydrolysis of the α-1,4 glycosidic bonds in soluble starches and related subsrates. These substrates are broken down to release short oligosaccharides and α-limit dextrins.
