General description

α-Amylases are endoglycosidases, that are classified into glycosyl hydrolase family 13 (1-3).[1]

Application

α-Amylase Inhibitor from Triticum aestivum (wheat seed) has been used to determine its effects on salivary gland (SG) amylase activity.[2] It has also been used to inhibit the activity from the extract from Bemisia tabaci.[3]

Biochem/physiol Actions

α-Amylases can hydrolyze α-(1,4)-D-glycosidic linkages. It participates in the breakdown of starch and glycogen. Inhibiting this enzyme can be used as a strategy to treat dental caries, diabetes, obesity and periodontal diseases.[4]
Competitive inhibitor of human salivary α-amylase. KI = 2.9 nM, compared to a KM of 5.9 mM (calculated per mole of α-1,4-linked maltose residues).

Unit Definition

One unit will reduce the activity of two units of α-amylase (A0521) by 50% after pre-incubation at 25 °C.

Physical form

Lyophilized powder containing buffer salts as sodium phosphate.
