FunFam 13847: Alpha-amylase, putative (AFU_orthologue AFUA_2G134...

There are 10 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.

1,4-alpha-glucan branching enzyme. [EC: 2.4.1.18]
Transfers a segment of a (1->4)-alpha-D-glucan chain to a primary hydroxy group in a similar glucan chain.
  • Converts amylose into amylopectin.
  • The description (official name) requires a qualification depending on the product, glycogen or amylopectin, e.g. glycogen branching enzyme, amylopectin branching enzyme.
  • The latter has frequently been termed Q-enzyme.

Glucan 1,4-alpha-maltohexaosidase. [EC: 3.2.1.98]
Hydrolysis of (1->4)-alpha-D-glucosidic linkages in amylaceous polysaccharides, to remove successive maltohexaose residues from the non- reducing chain ends.
  • Cf. EC 3.2.1.3, which removes successive glucose residues.
  • Cf. EC 3.2.1.2, which removes successive maltose residues.
  • Cf. EC 3.2.1.116, which removes successive maltotriose residues.
  • Cf. EC 3.2.1.60, which removes successive maltotetraose residues.
  • The products have the alpha-configuration.

Cyclomaltodextrinase. [EC: 3.2.1.54]
Cyclomaltodextrin + H(2)O = linear maltodextrin.
  • Also hydrolyzes linear maltodextrin.
  • Formerly EC 3.2.1.12 and EC 3.2.1.13.

Pullulanase. [EC: 3.2.1.41]
Hydrolysis of (1->6)-alpha-D-glucosidic linkages in pullulan, amylopectin and glycogen, and in the alpha- and beta-limit dextrins of amylopectin and glycogen.
  • Different from EC 3.2.1.142 in its action on glycogen, and its rate of hydrolysis of limit dextrins.
  • Its action on amylopectin is complete.
  • Maltose is the smallest sugar that it can release from an alpha- (1->6)-linkage.
  • Formerly EC 3.2.1.69.

Neopullulanase. [EC: 3.2.1.135]
Hydrolysis of pullulan to panose (6-alpha-D-glucosylmaltose).
  • Cf. EC 3.2.1.41 and EC 3.2.1.57.
 4 G4FGM1 G4FGM1 Q9X2F4 Q9X2F4
Glucan 1,4-alpha-maltotriohydrolase. [EC: 3.2.1.116]
Hydrolysis of (1->4)-alpha-D-glucosidic linkages in amylaceous polysaccharides, to remove successive maltotriose residues from the non- reducing chain ends.
  • Cf. EC 3.2.1.2, EC 3.2.1.60, and EC 3.2.1.98.
  • The products of all these enzymes have the alpha-configuration.

Purine nucleosidase. [EC: 3.2.2.1]
A purine nucleoside + H(2)O = D-ribose + a purine base.
  • The enzyme from the bacterium Ochrobactrum anthropi specifically catalyzes the irreversible N-riboside hydrolysis of purine nucleosides.
  • Pyrimidine nucleosides, purine and pyrimidine nucleotides, NAD(+), NADP(+) and nicotinaminde mononucleotide are not substrates.

Glucan 1,4-alpha-maltohydrolase. [EC: 3.2.1.133]
Hydrolysis of (1->4)-alpha-D-glucosidic linkages in polysaccharides so as to remove successive alpha-maltose residues from the non-reducing ends of the chains.
  • Acts on starch and related polysaccharides and oligosaccharides.
  • The product is alpha-maltose; cf. EC 3.2.1.2.

Alpha-glucosidase. [EC: 3.2.1.20]
Hydrolysis of terminal, non-reducing (1->4)-linked alpha-D-glucose residues with release of alpha-D-glucose.
  • Group of enzymes whose specificity is directed mainly toward the exohydrolysis of 1,4-alpha-glucosidic linkages, and that hydrolyze oligosaccharides rapidly, relative to polysaccharides, which are hydrolyzed relatively slowly, or not at all.
  • The intestinal enzyme also hydrolyzes polysaccharides, catalyzing the reactions of EC 3.2.1.3, and, more slowly, hydrolyzes 1,6-alpha-D- glucose links.
