The direction shown, i.e. which substrates are on the left and right sides, is in accordance with the direction in which it was curated.

Mass balance status: Balance undetermined; a substrate has a non-numerical coefficient

Enzyme Commission Primary Name: α-amylase

Enzyme Commission Synonyms: glycogenase, α amylase, α-amylase, endoamylase, Taka-amylase A, 1,4-α-D-glucan glucanohydrolase

Taxonomic Range: Archaea, Bacteria , Fungi, Viridiplantae, Metazoa

Enzyme Commission Summary:
The enzyme catalyzes the endohydrolysis of (1→4)-α-D-glucosidic linkages in polysaccharides containing three or more (1→4)-α-linked D-glucose units.

Acts on starch, glycogen and related polysaccharides and oligosaccharides in a random manner; reducing groups are liberated in the α-configuration. The term "α" relates to the initial anomeric configuration of the free sugar group released and not to the configuration of the linkage hydrolysed.
