IPR006046 is a Alpha amylase.
<p>O-Glycosyl hydrolases ([ec:3.2.1.]) are a widespread group of enzymes that hydrolyse the glycosidic bond between two or more carbohydrates, or between a carbohydrate and a non-carbohydrate moiety. A classification system for glycosyl hydrolases, based on sequence similarity, has led to the definition of 85 different families [[cite:PUB00004870], [cite:PUB00005266]]. This classification is available on the CAZy (CArbohydrate-Active EnZymes) website.</p> <p>Alpha-amylases, which belong to glycoside hydrolase family 13, are 1,4-alpha-D-glucan glucanohydrolases, which degrade both the branched and unbranched forms of starch by cleaving the internal alpha-1,4 bonds connecting the glucose monomers. The products of these reactions are maltose and maltotriose, which are further degraded to glucose by maltases. One atom of calcium is required to bind to each protein molecule to allow it to function, but excess calcium can inhibit activity by binding to amino acids that are required for the catalytic activity of the enzyme.</p>

GO predictions are based solely on the InterPro-to-GO mappings published by EMBL-EBI, which are in turn based on the mapping of predicted domains to the InterPro dataset. The InterPro-to-GO mapping was last updated on , while the GO metadata was last updated on .
| GO term | Namespace | Name | Definition | Relationships |
|---|---|---|---|---|
| Molecular function | Catalytic activity | Catalysis of a biochemical reaction at physiological temperatures. In biologically catalyzed reactions, the reactants are known as substrates, and the catalysts are naturally occurring macromolecular substances known as enzymes. Enzymes possess specific binding sites for substrates, and are usually composed wholly or largely of protein, but RNA that has catalytic activity (ribozyme) is often also regarded as enzymatic. | ||
| Biological process | Carbohydrate metabolic process | The chemical reactions and pathways involving carbohydrates, any of a group of organic compounds based of the general formula Cx(H2O)y. Includes the formation of carbohydrate derivatives by the addition of a carbohydrate residue to another molecule. | ||
| Molecular function | Cation binding | Interacting selectively and non-covalently with cations, charged atoms or groups of atoms with a net positive charge. |
