Biochem/physiol Actions

α-Amylase is composed of 496 amino acids in a single polypeptide chain. It 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

Lyophilized from Tris buffer containing NaCl and CaCl₂.

Preparation Note

Prepared by modified method of Levitzki et al.

Other Notes

One unit will liberate 1.0 mg of maltose from starch in 3 min at pH 6.9 at 20 °C.
