alpha-Amylase from Bacillus licheniformis, Type XII-A, saline solution, >=500 units/mg protein (biur

Descriptions

Application

?-Amylase is used to hydrolyze ? bonds of ?-linked polysaccharides, such as starch and glycogen. Product A3403 is from Bacillus licheniformis and is type XII-A. ?-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.

Caution

Reported to be heat stable at temperatures as high as ~90?°C.

General description

?-Amylase is a member of the endo-amylase family. Its molecular weight is 57.6 kDa. ?-Amylase is composed of three functional domains namely A, B and C. Domain A is a barrel-shaped (?/?)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 ?-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.
