General description
α-Amylase is a member of the endo-amylase family. Its molecular weight is 57.6 kDa. α-Amylase is composed of three functional domains namely A, B and C. Domain A is a barrel-shaped (β/α)8 structure and is the largest domain. Domain B is linked to domain A via disulfide bond and is present between domain A and C. Domain C is composed of β-sheets and is connected to domain A via a polypeptide chain.

Application
α-Amylase is used to hydrolyze α bonds of α-linked polysaccharides, such as starch and glycogen. Product A3403 is from Bacillus licheniformis and is type XII-A. α-Amylase, from Sigma, has been used in various plant studies, such as metabolism studies in Arabidopsis .
Biochem/physiol Actions
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.
Physical form
Aqueous solution containing sodium chloride and sucrose
Other Notes
One unit will liberate 1.0 mg of maltose from starch in 3 min at pH 6.9 at 20 °C.
