FunFam 7239: Alpha-amylase 1

There are 3 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
Alpha-amylase. [EC: 3.2.1.1]
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.

4-alpha-glucanotransferase. [EC: 2.4.1.25]
Transfers a segment of a (1->4)-alpha-D-glucan to a new position in an acceptor, which may be glucose or a (1->4)-alpha-D-glucan.
  • An enzymic activity of this nature forms part of the mammalian and Saccharomyces cerevisiae glycogen branching system (see EC 3.2.1.33).
  • Formerly EC 2.4.1.3.

Cyclomaltodextrin glucanotransferase. [EC: 2.4.1.19]
Cyclizes part of a (1->4)-alpha-D-glucan chain by formation of a (1->4)- alpha-D-glucosidic bond.
  • Cyclomaltodextrins (Schardinger dextrins) of various sizes (6, 7, 8, etc. glucose units) are formed reversibly from starch and similar substrates.
  • Also disproportionates linear maltodextrins without cyclizing (cf. EC 2.4.1.25).
