3.2.1.1 |
| Accepted name: |
α-amylase |
| Reaction: |
Endohydrolysis of (1→4)-α-D-glucosidic linkages in polysaccharides containing three or more (1→4)-α-linked D-glucose units |
| Other name(s): |
glycogenase; α amylase; endoamylase; Taka-amylase A; 1,4-α-D-glucan glucanohydrolase |
| Systematic name: |
4-α-D-glucan glucanohydrolase |
| Comments: |
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. |
