Enzyme Information

3.2.1.1
Alpha-amylase.
based on mapping to UniProt P56271
Endohydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides containing three or more (1->4)-alpha-linked D-glucose units.
-!- Acts on starch, glycogen and related polysaccharides and oligosaccharides in a random manner; reducing groups are liberated in the alpha-configuration. -!- The term 'alpha' relates to the initial anomeric configuration of the free sugar group released and not to the configuration of the linkage hydrolyzed.
