ENZYME entry: EC 3.2.1.1

Accepted Name
Alpha-amylase.
Alternative Name(s)
Glycogenase.
Reaction catalysed
Endohydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides containing three or more (1->4)-alpha-linked D-glucose units
Comment(s)
  • 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.
