Description

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.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in starch ethanol research. For more information see the article in biofiles.

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

1 U setzt 1.0 mg Maltose aus Stärke in 3 Minuten frei bei pH 6.9 und 20 °C.
